I have been seeing Dr. Niles for my dental care for over 30 years. She's a fine dentist and does a great job. Her staff are very friendly as well. I would highly recommend her.

One of the best dentists in town! Always concerned about making sure that you don't have pain...very technically adept and business-like. gives you a real sense that she knows what she's doing. Able to save a tooth that I'd broken off at the gum line with a metal post and crown. worth every penny! Staff is great as well.

I have been a patient of Dr. Niles since 1998. Even though I now live two hours away, I still commute back to Santa Rosa for appointments because I always receive first-rate care and go home feeling happy. The staff is amazing - from the front desk to point of care - and always send me home with a smile (and a better-looking one at that).
