Especially for a place that doesn’t specialize in pediatrics, the staff went above and beyond for my 3 year old. The hygienist and dentist explained everything and answered all her questions. I’m very grateful to have found this office for my family.

Best Doctor, amazing nurses. From the front desk to the whole process it was a 10/10. Everyone was very kind, the doctor explained everything to me in detail so I knew what was happening every step of the way.

Karen R.

Extremely pleased with the services I received from Dr. Nagy and her assistant Kiara! At the onset, I was quite anxious about a tissue graft and didn’t know what to expect. Two weeks later, I can truly say that their treatment and results were beyond GREAT! Thank you both for your expertise and kindness!

Susan L.

My visit was astonishing. I went for my first visit for my cleaning. Jessica Pawlowski was my hygienist. She was so professional and helpful. My mouth was so light that I was able to feel my teeth so light and fresh. I strongly recommend her services. Thank you very much.
