Happy Client from Mercer Island Office“They are awesome! Took care of my four kids today super convenient!”
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.”
TJ Burke
Happy Client from Mercer Island Office“Love the care, personnel and extra special treatment I receive with every visit. Best dentist I have ever had!”
Betsy Tutland
Happy Client from Mercer Island Office“Dr. Thomas is an amazing dentist. At both his Mercer Island and Kirkland offices the staff is very warm and welcoming. Dr. Thomas has been my husband’s and my dentist for over 20 years and has done exceptional dental work. He makes his patients feel at ease with his caring, positive and fun personality. My grandchildren also see Dr. Thomas and he has an amazing way of helping them to feel comfortable and thus, cooperative. Dr. Thomas has the highest medical and ethical standards. I highly recommend seeing Dr. Thomas for any dental procedure.”
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.”
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.”

Happy Client from Mercer Island Office“I can't recommend this practice enough. Everyone who works here is courteous, professional and extremely competent. 10/10”
Vanessa Hoffman
Happy Client from Kirkland Office“This was my first dental visit and I must say they were definitely unorganized as their X-ray machine kept freezing the images delaying my appointment and they’re not put together. The manager Carmen told me I was going to have to pay a $70 balance. Which I completely agreed on no problem. I got a bill for $140 and was never told I had a $50 co-pay on top & they don’t use silver filling so I had to pay extra for a white filling. I was not told about any of these extra charges. The manager Carmen hung up on me over the phone without trying to fully explain everything and was very rude to me. I would not recommend this dentist because they are not truthful and they want you to pay double your bill so please be careful.”
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.”
Dennis Ferrer
Happy Client from Kirkland Office“Nice, smart and they do a great job”
Chelsey Swan
Happy Client from Kirkland Office“I love Thomas Dentistry! Tracie is my usual hygienist. It might be strange to say, but I enjoy my teeth cleanings here. They are so easy and, as far as dental work goes, as comfortable as they can be.”
kirk packard
Happy Client from Kirkland Office“I have had a ton of dentistry done and have been to alot of dentists. These folks have it together. Just had a molder crown replaced. Quick ,completely painless and my bite is perfect 1st try. Absolutely no adjusting and then they repaired a front tooth I had broken after quickly epoxy in molder. This was the 2nd appointment to install crown and I was only in the chair 20 min. Went like clockwork and looks awsum. Thanku. Only thing better would be free haha!”
Patrick Dion
Happy Client from Kirkland Office“Best dentist I’ve ever been to. Not only are they prompt and quick but they walk you through your care clearly and explain the how’s and why’s. For once if feels like having an office that has a comprehensive plan for me rather than me checking a box every year. The hygienists are empowered to spend time with you and even book appointments with them right in the chair. Could not recommend more.”
linda
Happy Client from Kirkland Office“Had my teeth cleaned today again by Rosie. She is an excellent Dental hygienist. Takes the time to answer all my questions and is very informative. Greatly appreciate it.”
Ankita Joshi

Epic Heart Healing
Happy Client from Mercer Island Office“As always Dr. McNabb did not fail to impress! We are very fortunate to have him as our dentist . But I also wanted to lift up NADIA who cleaned my teeth this time around and did such an AMAZING job. She is really good at what she does, and has such a calming and personable way about her. Highly recommend these guys!!!”
Nelson Lopez
Happy Client from Mercer Island Office“Very very exceptional service, from making the appointment all the way to check out.”
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? ❤️”
Adrestia Frontida
