Happy Client from Kirkland Office“Tracie Was fantastic! Thank you”
Mary Berry
Happy Client from Kirkland Office“Very incompetent doctor dr. Thomas is after money. Don't believe anything he is saying. Other doctors are all recent college graduates with no experience. Don't trust them. Get a second opinion or just go some place else get your teeth done.”
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.”

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.”

Linda Scott
Happy Client from Kirkland Office“I visited Thomas Dentistry as a new patient on 9/9/21 and was impressed with their friendliness and professionalism. While there, multiple staff joined in to help resolve a personal issue, for which I was very appreciative. My husband and I will definitely schedule again with Thomas Dentistry Kirkland, and I’ll recommend them to family and friends.”

Faith Hutcherson
Happy Client from Kirkland Office“Really enjoyed my experience here for a teeth whitening. The Kirkland location is great; it’s close to the freeway so it’s easy to find, and there was designated parking for patients. The staff (I’m talking from front desk to assistants to the doctor) were all very friendly and extremely efficient. I was talked through what they were doing so I felt at ease the entire time.”

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.”

Ernest Heassler
Happy Client from Kirkland Office“Friendly, professional high quality dentistry. I made this observation two years ago and it is still valid. I can't imagine going elsewhere for dental care.”
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.”
Edward Estrada
Happy Client from Mercer Island Office“Efficient and kind staff! I went through a period of dental anxiety and my transition to this office was smooth and uneventful. They have decent hours, good parking, a great playlist, and refer to good endodontists. What’s not to love? ❤️”

Milo
Happy Client from Kirkland Office“Great dentist! I came after Covid for my first checkup and cleaning, and ended up needing to have some childhood crowns replaced. During the process they were very thorough, even once getting a crown remade to have a perfect fit. One of those visits came in under the estimate. I appreciate the care they take in their practice. The staff are always nice and fun to talk to. Since my first series I’ve come here for over a year and have always had great experiences. Still need to floss more but the dentists and assistants are super nice about it! Also have great reminder system, and are very patient and thorough when working on insurance issues.”
