“This is the best dentistry in the PNW! Molly at the front desk is so kind and always makes me feel like one of their VIP clients. The dental hygienists are all kind and Doctor Thomas is a straight shooter. Both myself and my Mom visit this office and couldn’t recommend it more!”
Mark Detrow

“Had such an amazing experience, and I would highly recommend coming here. I was incredibly thankful especially for how helpful and sweet Marna was. I typically do not like going to the dentist but she made me feel very comfortable and did a wonderful job! Will be back here soon!”
Madeleine Dow
Happy Client from Mercer Island Office
“Dr. Nguyen and the dental hygienists are super nice! I felt comfortable and safe—even the time I started crying when I had a panic attack before getting some cavities filled. (Sorry about that lol.) Anyways, Dr. Nguyen was very kind, gave me space to chill out, and didn’t make me feel embarrassed, even though I wouldn’t have blamed him if he did.”
Ronald Folse
Happy Client from Kirkland Office
“I’vy been a patient with Dr Troy for fifteen years and have always been impressed with him and his entire staff. I am 86 years old and was hesitant to make my visit, but his whole staff used the best practices to insure the safety in the office. Unfortunately , I will be moving to California ima month or so and will have to find a new dentist , and hope that they will be as good as Dr Thomas and his staff.”

Peter Christian
Happy Client from Mercer Island Office
“I did not have a dentist in the Seattle area and choose Thomas Dentistry because they were close and nearby. Boy, did I strike gold! I hadn't been to the dentist in a while and I needed some work done to get clearance for a other medical procedure. They were so great in getting me set up and expediting my treatments. Everyone was very professional and friendly. I can highly recommend them for your dental work.”
