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.”

Holly Yee
Happy Client from Kirkland Office“Such a wonderful dentist's office! The staff is always welcoming, efficient, and they do a great job with my oral care. The other day I had a tooth brush bristle stuck in between two of my teeth and needed to come in for a minute visit. They got me in that day and were able to remove the bristle. It was such a relief! Going to the dentist can somethings be uncomfortable, but at Thomas Dentistry I always feel taken care of.”

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.”
