Our Doctor:

Dr. John Nista

I was born to be an Orthodontist!

I have tremendous passion for our profession and the patients we serve. I feel privileged to be part of a profession that makes such a profound difference in people’s lives. My staff is vitally involved in this process and helps support our patients at every step of their journey. Straightening teeth is part of what we do but the entire GNO team strives very hard to help people enrich their overall lives.

We view our practice like one big happy family. We reach out to help each other and our patients in any way possible. We cherish the friendships we develop and constantly strive to encourage our patients to be the best that they can be. Our office is a warm, nurturing, fun place to be. There is no other profession we would rather be in. We love what we do! That’s what you can expect from GNO.

Dr. Nista’s personal interests include golf, fishing, skiing and cooking. He is an active member of the Knights of Columbus and is currently participating in Creative Mentoring. He, too, is a past President of the Delaware State Dental Society. Dr. Nista is married with two children, Jason and Sarah. Being the oldest of five children, he particularly enjoys working with young children.
