Patient Reviews
"All around a great experience! We had been told at another local ortho that there was nothing we could do for my son at his age so I just wanted a second opinion. We went in and they explained everything and said they could absolutely do something to help us if we wanted it done. Then after we said we wanted to move forward they immediately put him in the chair and put his braces on!! We were in and out with braces in under 90 mins! Absolutely awesome!!!!"
"The staff is WONDERFUL!!! My granddaughter and I had anxiety about her getting braces and me getting Invisalign but the Dr and her team put us both at ease. From answering questions, setting up payments and scheduling.Thank you"

Every time I went in and brought up a small flaw that was bothering me, they went above and beyond to fix it. I will recommend Greeley & Nista to everyone from now on! 100% in love with my results!"
"My daughter is 16. 3 years ago my daughter got braces due to a tooth that came in after her baby tooth but wouldn’t drop down like it was supposed too. Thanks to the GNO, with Braces and adjustments the tooth is in its normal spot plus my daughter’s teeth look great. Nice and straight."
"So very pleased with our experiences here at Greeley and Nista Orthodontics. Our daughter was very, very nervous and hesitant about getting braces. From day one, the staff were wonderful and created a welcoming environment where our daughter feels comfortable. Dr. Nista left a very nice phone message welcoming our daughter to his practice. Through visits he checks in as well. His team is wonderful and they explain to our daughter what they will be doing so she feels comfortable. We are very pleased with this practice and we recommend it to anyone in need of braces."
"Very good service! Had braces be put on in late 2021 and was able to get them taken off late 2023! I love the brace bucks system! My daughter was able to save up, and have enough to buy a10$ roblox card, which is awesome sauce! 100% recommend! Thank you!"
"I highly recommend GNO! Dr Nista and Dr Leah are incredible, professional and friendly. The office staff make every single visit enjoyable. They are always so happy, kind, and ALWAYS ran on time or early. ALWAYS. My daughter just got her braces off today. She had a very complex case. She was allergic to the nickel wires, had a tooth come in backwards, has a missing permanent tooth, etc. Nothing was ever a big deal to the doctors or staff. I was always confident she would end up with the most incredible smile (and she has). My daughter, Kayla, also has Down syndrome and some sensory issues. The staff treated her like a rock star and were always so great with her! I recall dreading going to my orthodontist- Kayla looked forward to her appointments. Lol. I really cannot recommend GNO enough. So grateful for their entire staff!"
"Thanks for helping me, as an adult, get my teeth back to my best smile! 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 glad I found Greenley and Nista who are so great to work with and made me proud of my smile again! Our family are big fans! My husband even decided to get on a plan with them as well :)"
"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. Choose Dr. Nista if you are thinking about getting braces! You will not get better care anywhere else!"
"I absolutely love this office ! The assistants and front desk girls are amazing . Everyone is so welcoming here and Dr . John Nista is the best I have ever came across in Delaware .

He answered their questions and addressed them directly! I don't know of any doctor who calls you the night before to introduce himself!I would highly recommend!"
"We love GNO. My daughter got her braces off today after 18 months. Her teeth look perfect, and she is so happy. Both Dr Nista and Dr Li are wonderful, great with kids, and the staff is so helpful, friendly, and accommodating. And Angela is the best ortho tech! Thank you for taking such great care of us!"

"My daughter is 14 and has had her braces on for about 7 months now! We really love the atmosphere and everyone you encounter is always extremely friendly and personable. Some offices when you call them if your running a couple minutes late will be rude or make you feel uncomfortable but not Greenley and Nista! They are very understanding and always make us feel welcomed and comfortable. It’s also a plus + that they have delicious Chocolate Chip Cookies 🍪 or if it’s a morning appointment, they have little munchkin donuts 🍩"
"This is the best place to come to for braces . Both the staff along with Dr.Nista are the bomb.com. Dr. Nista and I instantly connected since we’re both die hard Steelers fans. Now I’m the known as the steeler girl lol I am so thankful for all they have done for my teeth and I. Dr.Nista and along with his staff both listen , communicate well, listen , and truly care about all concerns , and questions . Not only will you walk out with your teeth fixed but you will develop a relationship with everyone for a life time ."
"The doctor was professional and great with my daughter. The facility is clean and well maintained. With the help of the facility my daughter was able to get her braces off a couple months early."
"My consultation visit at G and N was amazing! I had braces before and wanted to explore the option of getting them again. The staff was very kind when setting up an appointment by phone and it was easy to do. Dr. Nista called the day prior to my appt and made an introduction, which was so personable and made me even more excited. Upon arriving at the practice, Kathy took me back and did my intake. She is a ball of sunshine!! Very kind and personable. She educated me and made me feel comfortable, every step of the way. The treatment options provided were perfect for my needs and easy to understand. Customer service is a top priority to me and I am glad I chose this practice. Please give them a call, you won’t regret it!"
"My family and I have been patients of Greeley and Nista for almost 10 years! I have nothing but great things to say about them! They offer multiple payment plan options, a rewards program for children and adults, and who doesn't like a cookie or Donut AFTER your visit!! Oh yeah the most important thing... their braces are great🤣! Our teeth still look great! The entire staff is pleasant!! This is a great place for the entire Family!!"
"I brought my oldest son to the establishment , staff were very friendly and interactive. I appreciated the doctor reaching out prior to the visit. Most importantly they asked my son his opinion and thoughts about getting braces."
"I had my Invisalign treatment done here with Dr.Nista. My experience with the office and Dr.Nista has been nothing short of excellent. From the beginning I was communicated accurately on what I should expect. This is a very professional office and they’re incredibly helpful. I finished my 40 week treatment today and my teeth look great! If there is anyone who is looking at treatment I would 100% recommend going to Dr.Nista’s office. I was not disappointed and I’m sure many would agree."
"We had our consultation today and my daughter actual left with braces on! The staff were all very friendly, helpful, and efficient. Dr. Nista was great; he took the time to explain everything to my daughter and ease her anxiety about braces. We will definitely recommend GNO to our friends and family!"
"Our eighth grader got her braces off yesterday which completes our many years at GNO. Thanks to Dr. Nista and his entire staff including the technicians and front desk personnel we now have five beautiful smiles in our family. Dr. Nista not only creates beautiful smiles but does so in a professional and friendly manner. His entire staff is competent and wants to do right by each and every patient. I highly recommend this practice for both regular braces as well as Invisalign."
"6.15.2020 was my consult visit and it was great. Dr. Nista called me the night before and welcomed me as a new patient. When I got there the staff was so nice and just easy going. You could tell it wasn't being forced or fake. Dr. Nista and Kathy walked me through everything and told me up front what they could and couldn't do. I was able to get an appt right away for my consult and next week I will be getting my braces.Update 10.28.21- I got my braces off and I love my new smile. I had so many gaps in my teeth and now I have none. I couldn’t be happier about my results. The staff is very nice. There was no pain get them on/off. Dr. Nista is very nice and friendly, he is always excited to see his patients and I was always greeted with high energy and a smile. Bonus: I was able to get my braces off 4 months early."
"I was very nervous about seeing an orthodontist for my son who is 14 years old. They were extremely understanding, patient, and knowledgeable! I look forward to my son getting his braces on in the coming weeks, as well as the care that I know we will be receiving from Dr. Nista and his team."
"Staff is extremely nice and welcoming, very good with text and email reminders. Personally I was nervous about my visit but Maria was a great help and she makes you feel super comfortable.

I am looking forward to coming back to get my braces on and definitely would recommend them!"

"We have had four of our kids get their braces here and now I'm getting Invisilign. The staff is great and Dr. Nista is wonderful and a perfectionist. My dentist thinks he’s a miracle worker."
"It is never to late to get braces. Everyone was great! What a difference after my braces were removed."
"I was 33 when I started my braces journey and my experience was amazing! I was so concerned that I wouldn’t be able to be helped but I was assured everything was fine no matter my age or condition of my teeth. I was always comfortable l, no pain and was walked through step by step of what was happening with my teeth, what they were doing for that appointment and for my next appointment. 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"
"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."
"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."
"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."
"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 ❤️"
"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 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"
"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. Love this place can’t wait to see my final results :) if you need braces or you are thinking about getting them done I recommend you come to GNO. P.S. me and Dr. Nista are twinning today pink shoes ❤️❤️"
"The staff is wonderful! Im 33 and got braces and they made me feel extra comfortable. Thank you shanta for really keeping me comfortable.."
"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. I especially value how the practice takes the time to explain specific procedures and the patient's responsibilities with regard to their own treatment."
"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! My daughter had her braces taken off today after 2 1/2 years and we could not be more pleased with the results! She can’t stop looking at her perfect teeth and smiling. Wewill miss seeing and talking to everyone therebut we will be back! 😊 I highly recommendDr. Nista and his crew for anyone who needs orthodontic work done! Thank you againDr. Nista and your amazing techs! ❤️"
"Dr. Nista and his staff were friendly and made my daughter feel excited about getting her Invisalign done for her upcoming new smile. 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!"
"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!!"
"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 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!!!"
"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 got Invisalign as a teen and I love it. The staff is awesome and Dr. Nista is the best! Best ortho choice in Delaware!"
"Greeley & Nista is the best place for getting braces. I'm here with my niece and she absolutely lives the experience and is looking forward to getting her braces. What kid is excited? This kid!!!"
"Awesome office staff. Very knowledgeable and friendly. My 2 girls got braces on the same day in much less time then I thought. So glad I picked this place out of the 3 I got estimates at."
"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!"
"Greeley and Nista is the best orthodontics in the Newark area. I just had my braces removed today and I was so excited. They not only have the best staff they have an amazing office. 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. I feel like he only hires personel who acts just like him; gentle, caring, only worried about your experience. I can not stress enough how great this office is. If you are ever looking for an orthodontist in the Newark/Christiana area, Greeley and Nista is where you need to go."
"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!"
"I just love ❤️ this practice!!!

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."
"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!"
"Got my Invisalign this week and I’m so excited!!! Awesome staff"
"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!"
"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."
"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!"
"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."
"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 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!"
"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."
"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!"
"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."
"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."
"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!"
