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.

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

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!

I walked into the office for the first time today and was instantly welcomed. It was warm and cozy everybody had a smile you could feel the positive energy . Not only that but prior to my first appointment the doctor himself called me to introduce hisself . I'm very big on customer service and this placed definitely nailed it.

I recently moved to Delaware from New York and have a permanent/ bonded retainer on my lower front teeth. The glue on one of my teeth dislodged so I called this office to see if they would be able to repair it. The receptionist quickly dismissed me and said, and I quote, "We do not do that here." I thought this was an Orthodontist office and this is a pretty standard procedure/ quick repair. They didn't even try to schedule me to come in to assess. Unfortunately, I cannot go to my old Orthodontist who put the retainer on after I had braces SEVERAL YEARS AGO in high school because they are in New York. I will look for an Orthodontist elsewhere.

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
