Niles Family Dentistry is truly a gem. They are friendly and very professional. I appreciate how thorough the visits are and the staff not only do a good job they always explain what they are doing and are focused on the comfort of their patients. Dr Niles should be applauded for not only her professional knowledge and skill but for hiring a team of people who all have the same focus of the patient and work well together.

Everyone here is not only incredibly kind, but very knowledgeable and willing to answer questions, go over plan-of-attack details, etc. Everyone does a great job of explaining things, going over costs, any insurance hiccups or things to watch out for, you name it. Wish I would have found this place 6 years ago!


Niles Family Dentistry is a welcoming and comfortable environment. Our whole family is greeted by warm, friendly faces each time we come in.The staff is very helpful and knowledgeable. We could find a dental practice much closer to where we live, but we don't want to! Dr. Niles has created a lovely place that we want to come back to!

I am so thrilled to have found my new dental home after my dentist of 30+ years retired! The staff is extremely helpful and friendly. Your office is beautiful and so convenient to get to. Thank you! Thank you!

Great dentist and gentle, yet thorough hygienists who care about our family’s dental health. It’s a warm welcoming atmosphere and we’re always treated with kindness. Highly recommend.

As someone with severe dental anxiety Dr. Niles and staff has made me feel like a person who matters. Non-judgmental, kind and gentle. I am so happy to have found someone that I can trust to be straight forward but kind!! 10/10 the whole team is just spectacular!

Amanda B.

First visit with the Niles Family Dentistry. Very professional, clean, and low stress friendly staff and service! I was very impressed with the dentistry knowledge and customer care by DDS Niles and my dental hygienist Tina. Although my first visit, I highly recommend them!

Dave S.

I love the customer service, Ashley is working with my oral surgeon and orthodontist and coordinating a very complicated situation. She is very attentive and does great work.

Don L.

Kim is a great hygienist who I can tell takes great pride in her work. She can read when someone may be uncomfortable and adjusts her technique to balance progress with comfort. Quick witted and funny I look forward to going back for my next checkup in 6 months!

Ivan O.

Dear Dr. Niles and Shannon: The whole experience was comfortable, gentle, and enjoyable-- and personal, even though you both wore masks for your well-being--I really liked how Dr. Niles lightly touched my forearm; that made the connection not just warm but very much in the present. Thanks for recommending a less "drying" toothpaste and fluoride. I'd like to try that. At Natural Grocers I have been buying a non-mint flavor from one of these two brands: Himalaya Botanique or Now Foods. At your convenience, please recommend a less "drying" toothpaste from one or both of these brands.
