I had a permanent retainer after braces from childhood on my bottom teeth fall out during 2020 when all the dentists were closed. My teeth moved in between new insurance, finding a new orthodontist after coming out of 2020, and getting time to take care of myself.

"I am getting close to being finished with my treatment at GNO… and I don’t think I could have had a better experience anywhere else. Dr. Nista has got to be one of the nicest orthodontists out there.I work at a dental office and constantly refer patients to him. My case has not be an easy one, with impacted canines- fun! 😆 But his level of patience and thorough care have been so so appreciated. When my adult teeth were being stubborn with coming down- instead of sending me back to the oral surgeon, he took the matter into his own hands and did a procedure right then and there!It has been nothing but a great experience.

During Covid everything was clean, all protocols followed and I felt safe to continue with my appointments as scheduled. I came in insecure and not happy with my smile and today 1/13/2020 I got my braces taken off (less than a year treatment) and I’m so happy and pleased with my results. The staff ALWAYS went above and beyond no matter what request or the 100000 questions I asked. I love the treatment and service I received and I will recommend anyone I know that wants to fix their smile to come here!! I wish my treatment was longer because you really feel like family even after your first visit!"
"Most people don't start their orthodontic journey later in life – but that's how it worked out for me. My first step in addressing my overcrowded and less than straight teeth came when I was in my 50's. I have to admit – I was nervous that it wouldn't even work. I have a lifetime of dental issues to accommodate – root canals, crowns and implants to name a few. I was nervous and not terribly optimistic – but I decided to give it a try. I chose Dr Greely because he managed both of my children's orthodontia with great results. He worked closely with my family dentist and periodontist to make a plan that worked for me. Success! After 18 months (a little longer than planned - thank you covid) I completed my Invisalign treatment today! No more crowded teeth – my smile is straight for the first time – ever. Invisalign is easy and it works – even for more mature patients like me.Dr Nista is a great guy – easy to talk to and work with and he runs a fun office with engaged, caring staff. It's not all pre-teens and teenagers. I felt very comfortable, each visit. If you, like me, have put off getting the smile you always wanted, call Dr Nista – you'll be happy you did!K.McG"
"Clean, professional and VERY friendly. It was my first visit and I enjoyed every moment of it. Everyone greeted me and was amazing at explaining everything each step of the way. I have to give a big shoutout to Kathleen who made my visit one to remember because of her kindness. Looking forward to my next visit."
"I was a patient of GNO 30 years ago, and there was no question about where I'd take my kids for their care. GNO explains treatments well and always makes visits fun. While Dr. Nista and his humor are a highlight of every appointment, each member of that office has made us feel special. I couldn't recommend them more!"
"Awesome experience! The staff at GNO are fun yet professional. Dr. Nista is the best! They made the process of wearing braces very easy. I would highly recommend them for anyone wanting braces, especially if you are an adult."
"What an amazing practice !! First time visit was today staff was super friendly and helpful! Great all around experience, we are here for this practice let me tell you shout it from the rooftop this is the place to go for your orthodontic needs !! Doctor Nista called me last night to introduce himself to me and welcome us to his practice you just don’t get that kind of customer service anywhere!! Highly recommend 5 stars ⭐️"
"Dr. Nista and the entire team are simply awesome! I'm almost halfway through my braces journey, and with the help of GNO it has been stress-free."
"Awesome place! Amazing people! My kids are happy!"
"When I first went to Greeley & Nista, I didn’t know what to expect far as how the entire process would be with braces.(all the horror stories I’ve heard from friends that has had braces in the past) But everyone in this office is extremely nice, passionate and hard working! They all care about how you are and everything. Such an amazing atmosphere to be in. I love everyone here and I’m slightly sad that I won’t be coming anymore for a tightening since my treatment is over lol😂. I’m so pleased with my results! Best Orthodonist and I would highly recommend to anyone who needs braces! Thank you Greeley & Nista for the best experience❤️"
"Received very good results from my braces. I came in with a pretty problematic bite and the changes are pretty drastic. I was able to get them off early, because staff worked with me to make it happen. I am thankful for the experience."
"We absolutely love the whole Newark office ❤️"
"Customer service at its finest... Dr. Nista called the day before the placement of my braces to welcome me as a new patient.. He also called me a week after the placement of my braces to see how the process is going for me so far... the staff at both Newark and wilmington are amazingly nice... this adds to the excitement of my journey.. thanks Dr. Nista, Elena and team"
"I went in for just a consultation and to see the office. Everyone from the receptionists to Dr.Nista were amazing. I was shown in detail the cost of braces and how long I’d have them. Got my braces put on the same day. So happy I chose this orthodontist to spend the next 18 months with ❤️"
"Very nice people , and flexible"
"My husband and I both had our braces here and we LOVE GNO! The entire office is like family -- appointments were always a breeze, admin staff/techs always helpful and friendly. I wouldn't trust anyone else with my/my husband's teeth. GNO is simply the best."
"I must say! Hands down, GNO is the best! Honestly!"
"My experience at Greely & Nista is always the same, your'e treated like family...very kind and you feel like you've known everyone for years..Highly recommend them..."
"I have been very pleased with Dr. Nista! He is warm and welcoming with children and makes us feel like part of a family. I have completed Invisalign as an adult with him, my oldest completed phase 1 treatment and my youngest is now getting ready to begin. Wonderful staff and office that comes highly recommended! Thank you for everything"
"Wonderful experience! And I love the staffing!"
"Greeley And Nista Orthodontics go above and beyond to ensure that their patients receive the best in orthodontic care! Dr. Nista and his team offer multiple cutting edge options for correcting any issue big or small. Beyond the amazing technicians and skilled orthodontists every staff member is professional, personable and accommodating. I was an adult patient in 2003 and I was so pleased that there was no doubt where my boys would be going. Each of us had a wonderful experience with amazing results. I highly recommend Dr. Nista and his staff for any and all orthodontic treatments!!"
"Today was my 2 month update apt for my braces. GNO is the best place that I could have chosen for my braces treatment. The staff is wonderful and everything always goes smoothly.

P.S. me and Dr. Nista are twinning today pink shoes ❤️❤️"

"Our kiddo has been a patient of GNO for over two years and today he started Invisalign treatment! Dr. Nista and the practice technicians and staff are very professional and caring.

"Love this place! Great staff and great results!"
"This group is always accommodating, they treat us like family and always provide us with exceptional care. The staff are welcoming and friendly. We couldn’t have asked for a better experience."

"I am a patient of Dr. Nista and currently in Invisalign. the price is great and the entire office is so friendly and helpful.Now it is my youngest daughter’s turn. She went for her consultation today and the staff and Dr. Nista made her feel very comfortable. Prior to our visit, me and my daughter each received a welcome letter, with a sheet for my daughter to fill out about herself (fav sports, hobbies, nickname, etc) The Price is very reasonable and my daughter felt very comfortable with the those she interacted with today. They always have something going on for the kids, which is currently a coloring contest to win $100. They give you the picture and paints, glitter etc., to complete your coloring page. My daughter chose her picture to color for the contest and we will post on FB for the judging.I highly recommend Dr. Nista and Team for your Braces/Invisalign experience : )"
"I cannot express how happy we were with Dr. Nista and his awesome staff! The Office and the patient area atmosphere is so warm and welcoming!

Dr. Nista even called the night before her appointment to introduce himself to us.I would highly recommend him to all my friends and family who are looking for an Orthodontist!!"
"Today was a real team effort at Greeley & Nista! Thank you to a great staff! The world is cautiously opening up and with that comes several medical appointments, particularly for my daughter who has been through a lot. She and I thought she was going in for a herbst check up or adjustment and to talk about her braces going on. With the great precautions in the office Catherine was let in first. When I got to the procedure area, unknown to me, the base part was already on the top and bottom teeth, I did not know this until Dr. Nista came over. I was upset that we didn't know it was braces day and that metal was the only option because of Catherine's mouth needs. I am praising the staff because when they saw that I was upset much of the staff cared to see what was going on, one technician brought over a model so that I could understand the procedure, another asked about our initial consultation which was a year or so ago, due to pandemic closings, there was no follow up consultation prior to today's appointment. Elaina (hope that is her spelling) is a RockStar!!! She communicated with other technicians as she was working on Catherine, she talked to her and encouraged her. Between Elaina and a couple of the other techs, I calmed down. Elaina had mentioned that it was an emotional day, I mentioned sensory overload, this included. We have a big family, Catherine is the first in our entire family to experience braces (some need them, but she's the first, lol!) At the end, we permitted hugs, (we were masked) Elaina hugged Catherine, then me, at that point the tears I held back came out, another tech touched my back. I subconsciously needed their care. As a mom (parent) we feel so much for our kids, Elaina is a mom and was very caring even as she walked us out. Catherine has so much in her mouth, but she has handled everything really well. Elaina did a great job, Catherine wears braces well. It looks like she's always had them. She is such a strong, beautiful girl. Thank you again to the Greeley and Nista staff!"
"The visits are always on time, staff is very pleasant and experienced. Dr.Nista is remarkable, always with a smile on his face, upbeat while being very professional. He is a perfectionist and your teeth have to be perfect. My son and I have used Dr Nista and are very very satisfied."
"Dr. Nista is the best. Office works with you and understands the impact on the cost of braces to a family. Couldn't ask for more from them they were so helpful"
"Greeley and Nista orthodontics is an amazing place. All the people who work there are extremely nice, and very welcoming. My son Elijah just got his braces off after 3 years. Never a complaint. They walked us through everything and answered every question. I would highly recommend this office!!!"
"Absolutely love Dr. Nista and his staff! My husband and two boys all had braces with Dr. Nista. Whether as an adult or adolescent, he’s caring, talented, and personable. His staff is equally as terrific!! Highly recommend Dr. Nista!!"

"I can not rave more about Dr Nista and his amazing staff. He took on the challenge of making room for canines when others wanted to extract permanent teeth. My son has a beautiful smile with all his permanent teeth retained!!! Thanks for all your hard work and dedication to my child and his teeth. ❤️🦷 You all are truly amazing!!!"
"Dr. Nista and his staff are amazing! They truly go above and beyond for all their patients! I would highly recommend him if you are looking for someone that pays attention to detail and goes the extra mile! We appreciate you ALL! Keep smiling! 😀"

"My oldest son just got his braces off! Dr.Nista and his staff have been so wonderful! It doesn’t matter if I’m calling to change an appointment, asking for a spur of the moment appointment because my son wants to ask a question about his treatment, or just the friendly smile and greeting you get every time you walk in that office- this practice is one of a kind!I have two other children that are both under Dr.Nista’s care, and I even decided to have Dr. Nista work on my teeth!Thank you Greeley & Nista Orthodontics!"
"I am a 28 year old adult that always wanted braces for the perfect smile. I’m actually 18months into the treatment plan and Dr.Nista and his team have definitely made me happy with my results so far! Dr.Nista does pay attention to each patient and answers questions. Price was great and the staff is very pleasant. Come here you’ll definitely be happy you did!"
"My daughter had an entirely positive experience with Dr. Nista and the technicians. Everything happened as described and within the expected timeframe. Highly recommend!"
"Love it here! Our family has been coming to GNO for our ortho needs for over 20 years. Now my 12 year old is here and they did not disappoint. The staff is fun and friendly, but most of all... professional."
"We have loved our experience here, we can’t say enough good things about everyone here.

Thank you so much!"
"My daughter and I have had a wonderful experience here with Dr. Nista and the staff. The entire team here makes you feel at home. Everyone is very compassionate and helps with any questions and or issues that may arise. Together we worked hard to make my daughter dreams come true! I will recommend Greeley And Nista to anyone I know needing braces. Thank you for everything!"
"Olivia was so excited to get her braces on! Thanks for making it such a fun experience!!"
"I decided to get braces when I was 46, and have been seeing Dr. Nista for 20 months now. He, and his team, are wonderful! From the first (very nervous) day I arrived, everyone treated me with kindness and respect, and they have always been available for questions, when I needed something fixed, and for my endless request for more bands :-) I am wearing the Damon metal braces, and Dr. Nista's expertise has kept my progress right on schedule with great looking results! When you're ready to take the plunge, I recommend that you make a visit to Greeley and Nista Orthodontics - they will be a partner in your journey."
"Thanks Allison Darling for being such an awesome orthodontist tech today! You did my adjustment and helped close a small gap that my braces were causing! Thanks so much!!!"
"Today was my daughter's last visit and she picked up her retainer. The office is inviting and the staff are friendly. The experience was better than I hoped for thanks to Dr. Nista and his team!"
"We had the best experience ever. The entire staff is amazing. I highly recommend Greely & Nista for your orthodontic needs!"
"Went into the office today for my son to get his Invisalign only to realize that I was a day early. Christy was amazing and so friendly. She was able to fit us in and work around other patients coming in. She saved me from having to take off another day of work to turn around and bring my son back into the office."
"I'm so glad I went to this orthodontist. Like its the best ever. Y'all should check them out, no pain, no sweat, no tears. They're gentle and kind, and its not that expensive I believe. I'm only 15 though so that should be enough to convince you. They're the best. (Thanks mom for bringing me here.) Love y'all thank you. 👍"
"We love GNO! This is our second round with our younger daughter and the experience is always positive for the kids. The office staff are extremely patient and helpful. We see the excellent results everyday when our eldest daughter smiles! :)"

"I just completed Invisalign with GNO and wanted to share my experience. First, everyone at GNO was great! I had an amazing experience as an adult patient. I highly recommend Invisalign. It was easy, painless, with only 4 appointments and the results are fantastic. I am extremely pleased with my smile. Thanks GNO."
"Just wanted to say a big thank you to Dr. Nista and his staff for helping me achieve my best smile. Being a dental hygienist, I help people with their teeth all day long and I finally took the time to get my teeth back in alignment (no I didn’t wear the retainer like I was supposed to after having braces as a child). I’m very pleased with my result and would highly recommend Greeley and Nista for all of your orthodontic needs. My daughter is now a patient of this practice as well and has done well so far with her “turtle.” Thanks for everything Dr. Nista and staff!"

They as staff make you feel so at home. When you walk into the office it is nothing but smiles and people willing to help you. Dr. Nista is an absolute angel! He is so gentle, caring, and is so worried about how you are feeling and how everything is going. He never is in a bad mood! Also, as a plus his pink converse bring out his bubbly personality.

If you are ever looking for an orthodontist in the Newark/Christiana area, Greeley and Nista is where you need to go."
"everything they do for us and more"
"I absolutely adore Dr. Nista and everyone in this practice.My son was in 3rd grade and very self-conscious about his teeth. Dr. Nista made him feel so comfortable and was so good about talking him through everything he was doing (expander, then braves).Fast forward to now, my son has the nicest smile and is so confident! We haven’t even started braces yet and the difference is amazing.Thank you Dr. Nista and team!"

Dr. Nista was amazing and my daughter left the office with no pain and jumping for joy with her new braces !!!Literally jumping!!!Forever grateful 🙏🏼Megan Welch"
"I visited Greely and Nista Orthodontics on January 20, 2016. At the age of 50, the one thing I had on my bucket list was to have my teeth corrected. I met with Dr. Nista and his staff. I had this wonderful invited feeling the first time we met. Every one was very friendly and professional. My braces had been removed November 14, 2018. My first response from family and friends was that I have a million dollar smile. I recommend if anyone need a orthodontist - please visit Greely and Nista Orthodontics. They are well worth it. To Dr Nista and staff, thank you and I miss you all. Love Priscilla Small ❤️"
"I have been treated at Greeley Nista Orthodontics for about 2 years.I had Invisalign braces for almost a year then finished off with some regular braces. My bite was corrected and the serious crookedness of my stubborn tooth. I am very pleased with the work this group has done. Doctor Nista and each technician I have had has done a very excellent job. Everyone in their office is great - I would recommend this orthodontist highly."
"My husband and both of our sons have been patients of Dr. Nista’s! He’s always looking out for the best interests of his patients and the best treatment plan for each patient. Both my husband and son were “difficult” cases, but both left Dr. Nista with an amazing smile and new found confidence! I highly recommend Dr. Nista!!!"
"My family’s experience with GNO has been beyond excellence without a doubt. We first met the team 9 years ago when our oldest became a patient. Her case was complicated and required more extensive interventions. The journey ended this week and we couldn’t be more pleased with the results! Our son, who has special needs, spent several years as well with the GNO team and Dr Nista was especially sensitive to his particular discomforts with treatment when he was younger. The staff are friendly and seem happy so a positive vibe just radiates throughout the office making appointments feel less like a chore. Thank you for all that you did to help our kids GNO !"
"Everyone in the office is so friendly and great atmosphere!"
"The staff there are absolutely outstanding they take amazing care of their patients and they extremely friendly and kind and by far I’ve ever met. I absolutely love them and I would recommend them to anyone and everyone."
"I came to Dr. Nista office to help me with my teeth , My teeth were very crooked, uneven I was unhappy and I wouldn't smile , I always covered my mouth or just kept my mouth closed But today I would like to Thank Dr. Nista and staff for being so pleasant, friendly , understanding, compassionate and showing so much love.. I can honestly say Dr.Nista gave me a beautiful smile with beautiful TEETH....Now I can smile and dont feel ashamed or embarrassed..... Today August 13, 2018 I got the greatest picture, hug and gorgeous looking teeth from Dr.Nista ... Thank you all so much.. Dr.Nista , my prayers to you and your staff, May God continues to bless you abundantly in all areas of your life.... Thank you with all my heart Linda....."
"I only gave Dr. Nista 5 stars, because that the most you could give. I had a wonderful experience with Invisalign retainers. I had a tooth that had almost twisted completely around on the bottom front. I figured I needed a couple of braces, but wasn't really looking forward to going through the process (probably the reason I waited as long as I did). Dr. Nista gave me the option of braces or the Invisalign process. I was skeptical, but decided to try them out. Wasn't completely sure it was going to work or if it would really be able to make the tooth come completely around and straight. Well, after 20 weeks, I was convinced that it was going to work. By 30 weeks, we were done. People that know me are commenting and can't believe that they actually worked as well as they did. Years ago, my son had a major construction project, over the course of several years, that needed to be done and that worked out great too! Dr. Nista and his staff are truly the best. I have never been to an office where everyone is always happy. The staff, truly loves their job and it shows. Dr. Nista is the one to go to if you need any type of ortho work. I know, I'm going to miss the positive environment, since my teeth are now done, but will always recommend anyone needing an Orthodontist to this office. He really is the best!"
"Dr. John Nista and his team are Awesome! I would give them 10+ stars! Highly recommend!"
"Way To Go Dr. Nista!!! You have created a wonderful environment that everyone wants when choosing a orthodontist."
"Dr. John Nista and his entire staff are awesome! Quality of care and making your orthodontic experience the best it can be is a priority for everyone in the practice and you know you are in the best hands. If it would allow me to give them 10 stars, I would. HIGHLY recommend Dr. Nista & his wonderful team!"
"Quick and friendly"
"Got my Invisalign this week and I’m so excited!!! Awesome staff"
"I would strongly recommend this practice. Dr. Greeley and Dr. Nista have called from there home to check up on my daughter and ask me if I had any questions or concerns. YouJust don't find that in a practice anymore!!"
"I love them!!"
"I needed orthodontic procedure done for a fairly significant chunk of time which also involved a major surgical procedure. Throughout all of it, all of the work they did on me was both efficient and effective. Everyone was nice and it all went well. I have nothing bad to say."
"Always on time, always professional and a pleasure to do business with. Well worth everyTrip we made from Jersey!"
"We love Dr. Nista! We are a family of 5, and Dr. Nista has treated 4 of us! We are all very pleased with our results and with the way we were treated at every visit. The best part about seeing Dr Nista is how friends and family notice how good our teeth look. My sister (who lives with the movie stars in LA) noticed how good my teeth looked after Invisalign and decided to get it for herself! Even my dentist and his hygienist complimented the results of my Invisalign. For someone who has had a lot of teeth problems, this is huge to me. For Dr. Nista, I appreciate all your patience and care! Thank you!"
"Our family loves the staff they are always so pleasant, willing to answer questions and an all around terrific orthodontic office! Dr. Nista is the best & Shanta is awesome. Thanks to the entire staff😀!"
"Great experience with Dr. Nista and the lovely ladies who gave me a great smile! :)"
"Dr. Nista and his assistant Chrissy did a superb job of gently placing braces on my lower arch today. They managed to actually make the experience very positive and personable. The office staff is friendly, accommodating, and encouraging. They took their time to answer my questions and to tell me what to expect as we go forward. I recommend them enthusiastically!"
"Kendal just left the office and is so happy with how her teeth turned out after having her braces off! Thanks again for making her experience so enjoyable!"
"I had the best experience at Greely and Nista Orthodontics. They made it very easy for me to balance being a college student and scheduling appointments. I just finished up with Invisalign a few days ago and couldn't be happier with my results. I was so impressed they were able to fix my underbite and cross bite all with Invisalign and it took no longer than about 15 months. The people there are very kind and I'm very glad I choose Greely and Nista."
"GNO Orthodontics is the BEST. I would highly recommend this practice for any one looking for an orthodontist. The entire process, from my consultation appointment to getting my Invisalign off exceeded my expectations. As a busy working professional the staff was very accommodating with appointment times. The office staff was very friendly, gentle and knowledgeable. I absolutely loved the dynamic between Dr. Nista and hygienists."
"My son had his braces removed today and we couldn't be happier with the whole experience. He started the process of orthodontic care when he was 6 years old and is now 16! From beginning to end, all of the staff was friendly and truly cared about his care. Both of my daughters also had braces and had the same wonderful experience! I highly recommend Greeley Nista Orthodontics!"
"I LOVE Greeley & Nista!!! I think I got braces in 1996 or 98, but I remember everything like it was yesterday. I just remember them being truly wonderful people. I remember they would always come check on me at the end of the appt. & they were just the nicest people & very proffesional!! They made every visit very pleasant. I recommend them to everyone. I might not have enjoyed every minute of having braces lol but that office/atmosphere was the best hands down!! I can't believe my smile today. When I look at pictures of myself when I was in gradeschool, omg not pretty lol. My grandfather still can't believe the results!! :) he cracks me up, but it's so very true. I love my smile!! Thank you Greeley & Nista!! Your amazing & I'm glad I was once apart of your practice!!"
"We couldn't be happier with our experience at GNO. Our daughter's braces came off yesterday and the results are great! From start to finish the entire process at GNO was friendly & professional. The entire staff was easy to work with, very caring and I would highly recommend them."
"I'm writing this review for my daughter Bridget. From beginning to end, we had a great experience with braces at GNO. Even when unexpected things happened like popping brackets, we could be seen quickly and conveniently. Bridget is all smiles now that the braces are off and she is really happy with the work that was done."
"Having never gone through braces, I didn't know what to expect when I took my son there. All I can say was Greeley & Nista orthodontics made this a pleasant experience. Very kind and caring staff and Dr. Nista is awesome. From start to finish, never a problem. I would highly recommend them!!"
"From my initial visit to Dr. Nista's office, the staff were friendly, warm and welcoming. Dr. Nista fully explained every step and every procedure that I would be encountering from the application to my removal. I absolutely love Christine, she was always pleasant, friendly and always greeted me like this was her first time meeting me. Even on the day I came in upset, she greeted with a hug. Coming to the office for the last six months has been a pleasure. When it was learned that my grandson need braces, I immediately brought him to Dr. Nista. Thank you for making my experience awesome. I highly recommend Nista and Greely Orthodontist to all my friends and family."
"Everything about my experience with GNO was professional, friendly and efficient. I never knew you could chew with your whole mouth until my bite was corrected. Looks and feels great... Connie is a perfectionist who obviously loves her work and does it so well! She is absolutely a delight to know and work with as is her whole staff.Go to the best... Connie Greeley!"
"I had the most wonderful experience with Dr. Nista and his entire staff. Everyone has been very welcoming and helpful since the very first consultation appointment. My treatment was super afforable and worth every single dollar. I have recommended GNO to my friends and family and I will forever say that they are THE BEST! I am so glad that I choose GNO to be apart of my transformation journey to a better smile."
"I'm from Utah and out here working in Delaware. The wires to my braces have been moving so they started poking and cutting up my cheeks! I called them up to see what they could do for me and they generously sent me to their technician to trim the edges down for me! For free! Just so I was taken care of! This place is hands down the best place ever! Now I sorta wish I lived here so I could get my braces done with them! So professional and they do such good work! 10/10 easy!"
"Absolutely fantastic experience from start to finish. Professional and helpful staff. Highly recommended."
"Our second child just got his braces off this past week. In both cases we were extremely pleases with the outstanding service we received from all of the Greeley and Nista people. The care, attention, and results were outstanding. Thanks!"
"My fourth and final child just had their braces removed and yet again we are delighted with the results. Each and every person we have interacted with was kind, helpful, friendly and courteous. I donot have one negative thing to say about our years of care. I would chose GNO all over again."
"I had a great experience her. Dr. Greeley and her team took great care of me at both offices. i couldn't have asked for a better experience and would highly recommend them for your orthodontic needs!"
"My son's experiences with both Dr. Greeley and Dr. Nista and the staff at Omega were wonderful. Everyone is friendly and pleasant. They take time to answer your questions and fit you in for an appointment when you have a problem. They were recommended to me by a friend and I highly recommend them."
"So many of my colleagues referred me to GNO. All my 3 kids had their braces there. The staff is so friendly and the hours are convenient. Their teeth look amazing.Thank you."
"I loved the experience at GNO. My daughter got her braces removed yesterday and she said that she is going to miss GNO.The staff at Greely and Nista orthodontist are fantastic,very friendly and professional. I loved the way they treat not only patients but also everybody else . Whenever I want to schedule or reschedule appointments the staff made the process very smooth. Totally I love GNO and would strongly recommend to friends and family."
"My experience at Greeley & Nista was nothing but pleasant. The staff are friendly all around, not only to the patients but to each other. I loved everything about Greeley & Nista from the happy and fun environment to the impeccable service. Nothing can beat the personal and caring relationships built with each doctor. Thank you so much for everything Greeley & Nista!"
"I knew before we had our first appointment that we would not be disappointed in the service or care we would receive at GNO! The Sunday evening before our first appointment Dr Nista called to welcome us and to see if we had any questions! We have had nothing but a great experience! Everyone has always been very nice, helpful and accommodating! I highly recommend GNO! They produce great results!"
"My daughter and I have had a great experience these past 2 years. Both Dr Greeley and Dr. Nista are super friendly as well as the entire staff we have come in contact with. You feel right at home in the office and always greeted with smiles. They are always respectful and courteous with scheduling and always worked with us. This has been a very pleasant and super casual experience overall. Thanks to all the staff and Doctors!"
"My daughter had a wonderful experience with Greeley & Nista Orthodontics. The staff was always kind and professional."
"Dr. Nista took care of both of my children over the past 10 years. He educated our family on the children's orthodontia needs and answered any questions we had with respect. His staff is amazing! Always cheerful and professional. Scheduling was easy, even when I had to change appointment times due to a conflict with my son's very busy athletic schedules. The accounting department was also very accommodating as our insurance situation changed during the course of our son's treatment. My son was thrilled when he cashed in his brace bucks for i-Tunes gift cards too! People still say how beautiful my daughter's smile is (10 years after treatment). We would recommend Dr. Greely & Nista Orthodontics to anyone needing orthodontia services. Thank you Dr. Nista and team!"
"My son had his braces removed today and he was actually a little sad......because he really enjoyed his experience with Dr. Nista, and the entire staff! Since the very first day we walked in we felt comfortable and at ease. The ladies at the front desk, the treatment coordinator, Terri, and the orthodontic technicians were all friendly and professional. Scheduling was never an issue nor was there ever a long wait time to be seen. Dr Nista really gives the personal touch from the first phone call to home to every visit taking an interest in my son. He was always a pleasure to deal with and his warm, caring and fun manner put my son at ease. My sons teeth look wonderful! Thank you! We would highly recommend Greely and Nista!"
"My son recently got his braces off after 3 years. We have both been very impressed with how professional and friendly Drs/ Nista and Greeley have been, as well as their entire staff. Every staff member has gone out of their way to accommodate busy schedules and even squeezed us in for a few emergencies here and there. The times we saw Dr. Nista or worked with one of the techs for wire replacements or adjustment, they were very friendly and informative of what they were doing and sharing feedback on how he was managing the care of his braces and wires. I would strongly recommend Greeley & Nista for anyone who needs orthodontic work. They are extremely knowledgeable, helpful, friendly and very personable. Great team!"
"Staff was wonderful!! We never had a problem getting an appointment at the times we needed. We never waited long in the waiting room. They always explained everything to us and most importantly, my daughter's smile looks incredible!!! One down 2 to go!!!"
"We have had the pleasure of having Dr. Nista as the orthodontist for not just my daughter but for myself as well. From the start, he as well as his entire staff has been wonderful! Everyone there welcomes each patient and family member as if they are all part of the Greeley/Nista family. While waiting in the chair, I have listened many times to how each individual person is greeted with enthusiasm and focused on as if they are the only one there at the time. Dr. Nista, along with the technicians, always want to know the latest happenings in the person's life as well as updates on the rest of the family. Dr. Nista has always been ready to receive and return my daughter's hugs, making her feel extra special. The atmosphere there is warm, welcoming, extremely clean and everything functions so smoothly, moving from the reception area thru the entire treatment area. This was my second time for having braces and I proved quite a challenge. One for the books, apparently. Thru it all, I was made to feel as though I was not a problem at all; instead they rejoiced with each bit of progress along with me. I would HIGHLY recommend Dr. Nista at this address, (never went to the other location nor did I meet Dr. Greeley)and have done so many times. To sum it up, in my daughter's words, "very good, very good, very good!!!""
"My two sons have received orthodontic services since 2006 from Dr. Nista and his staff. The staff at this office are always polite, caring, and professional. They have appointment times that work with my families busy schedule. In case of an emergency (brace bracket that brakes) they make sure that you are seen within 48 hrs. Also, Dr. Nista takes time to get to know his patients such as what school they go to, their favorite sports team, and what sport they play. To encourage young patients to take care their braces they offer "Brace Bucks" that can be collected and turned in for gift cards and other prizes. My family has always had pleasant experiences at every visit. I highly recommend Dr, Nista and his staff."
"Best Orthodontist period. Very professional caring staff. Gives back to the community."
"My son recently completed his whole phase....... his smile is amazing :) Staff is incredible and we couldn't be more pleased. Thank you!"
"The staff is excellent things have changed since I had braces (way back when) I would recommend this office to friends and family. Thank you for everything!"
"We thoroughly enjoyed our experience with G&O. The staff is very friendly and helpful, providing excellent service and also an affordable payment plan. The priceless confidence of a beautiful smile without breaking the bank. I will definitely recommend G&O to any and all who have dental needs."
"My daughter recently completed a many-year multistage orthodontic realignment of her teeth and we couldn't be happier. Throughout the entire project the office was always responsive and sympathetic to her needs and they were able to see her quickly on the rare occasion that she had an orthodontic emergency. I would strongly recommend this office for anyone who needs orthodontic work."
"Great experience when I went to Dr. Greely as a teenager. No brainer to bring my daughter to her practice with Dr. John Nista (GNO). Dr. Nista did an incredible job for my daughter, especially with getting through to my teenage daughter when it came to taking care of wearing her appliances and rubber bands. The staff is always friendly and attentive to the patients and family. I highly recommend GNO to anyone looking for orthodontic work.Keith Burlew"
"Everyone is really nice. My teeth are exactly how I wanted them. Can't thank you all enough!!THANK YOU"
"Enjoyed wearing the invisalign. Hard for people to notice i had them, unless they were up close and personal. My invisalign treatment took less than a year, which was an added bonus to them being clear braces. Overall, i loved wearing invisalign!"
"I got my braces off in 2005 and still have a perfect smile! Dr. Nista hasn't seen me in 10 years, but when I came in for an appointment today to get new retainers he remembered me and gave me a warm welcome back! He truly cares about each of his patients and gives all of them personalized attention. The staff is extremely friendly, the office is comfortable, and they have flexible appointment scheduling. I would never go anywhere else."
"We are very happy with Greeley & Nista Orthodontics. They are always efficient, cheerful and accommodating. Every visit was a pleasant one. I was always able to get appointment times to fit my schedule. My children had a good experience and their teeth came out beautifully! Thank you, Dr. Nista!"
"Both my son and daughter have gone through 2 phases of braces with Greeley & Nissta and I have been very happy with this office since our first visit. First was the expansion phase and then the braces phase. The office staff is the friendliest I have encountered anywhere! They are always cheerful and genuinely interested in the lives of their patients. My daughter loves the trivia questions Dr. Nista gives her from time to time at her appointments."
"Today was my daughter's final visit with Dr. Nista and I must say I was almost sad as he has been a big part of her life for several years. She first went to see Dr. Nista when she was 8 years old and her teeth were coming in rotated. We were informed upfront she would need two phases of braces due to her age and I must admit I was a little nervous about the expense at first but GNO made it so easy for us to afford that I soon was no longer worrying. Dr. Nista and his staff are always very fun, friendly and professional. The office runs on schedule so I never had to worry about sitting in the waiting room for a long time and the Brace Bucks program was a great little extra incentive for my daughter to take great care of her teeth. My daughter has gone from a little girl the wouldn't smile because of her crooked teeth to a beautiful young lady with a gorgeous smile and we have Dr. Nista and his staff to thank for that. I highly recommend GNO to anybody that is in need of orthodontic care."
"As an adult needing orthodontic care, GNO was recommended by my dentist, Dr. Mazoch. I was setup with Dr. Nista and after a 23 month treatment plan, I have a beautiful smile and much needed tooth alignment. My experience with the office staff was always pleasant and Dr. Nista worked hard to get the results that were sometimes questionable and challenging. I appreciated the patience, diligence, and never-ending encouragement with my care."
"I am a dental assistant and know that there are many offices to choose from. I checked a few offices out but it was clear that this was the office for me. The entire staff is very professional and everyone has a great personality. Dr. Nista is the best! He personally called me after my braces were put on and made sure everything was okay. I had the best experience and will highly recommend GNO to everyone!"
"We switched from another orthodontist, and GNO was a breath of fresh air. The office is modern, comfortable, and attractive. The staff is friendly and professional. Dr. Nista is always listened to our concerns, and answered all questions; he is genuinely concerned about his patients and their progress. His expertise is impressive: he inspires confidence. We are highly satisfied with our experience with GNO!"
"THANK YOU to ALL the Staff at Greeley & Nista Orthdontics!! You guys have been so Great and treated me like Family! I am beyond Excited and Happy with my results! My BEAUTIFUL SMILE speaks for itself!Thank You guys Again, Emy"
"Greeley & Nista were the orthodontist practice our dentist used for her own son when I asked her who she actually used for her own family. Greeley & Nista practice was extremely skilled, professional, efficient, friendly, personal, and they consider each patient walking out there in the community an example of "their work" so they want it to show and they want long-term optimal results. So because of this they are very available to inform patients, work flexibly with them, and make sure the patients know about and are invested in their results. The entire staff was very skilled at working with youth and getting good compliance, while also serving all types of patients. Dr. Nista and staff helped us clearly understand the technical aspects of why our son would benefit from orthodontic work, showing us pictures and measurements and spatial relationships that we had no idea were not optimal for reasons beyond just "straight pretty teeth." They helped us choose a treatment suitable to our circumstances. They were available and responsive always for questions, emergency appointments, etc. Dr. Nista did a great job getting a not-so-invested teen boy to have good compliance and great results - not a small feat! My son enjoyed going to his appointments and felt safe and comfortable in the office. As a parent I know that this practice gave me the BEST results they could, not just "pretty good" results. Dr. Nista truly takes pride in his work and the offices are run like well-oiled teams. We are very happy with our choice of Greeley & Nista Orthodontics, happy with the results, and heartily recommend them."
"Dr Nista did a Great job straightening my teeth. Everyone in the office is nice. Overall great experience. I love my new smile!"
