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.”
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.”

“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.”

“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!!!”
Chelsey Swan

“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.”

Elaina Sh
Happy Client from Kirkland Office
“Went to that office last year to get a crown on implant and Dr. Thomas did the ugliest crown possible. Shape and height looked completely different from natural tooth I had in that place before. He did not even try to fix it. This year my new dentist confirmed that the crown should have been done completely different but now Im stuck with this crown for a while because it will cost a ton to re-do it since that is a dental implant crown, not just a regular crown. I guess I missed the first red flag when they said they do root canals and extractions too. Of course, why even going to roots canals specialists and oral surgeons if You can get a “buffet of services” at Dr. Thomas! Also Molly at the front desk is the rudest receptionist I ve even seen, billing office could not get the numbers right and overcharged me for about $800 then refunded but can this office be more unprofessional and thirsty for money?!!”

Janelle Denson
Happy Client from Mercer Island Office
“I love coming here & I’m always greeted with smiles. It truly makes me feel great that the staff remembers my name & even though I visit every six months for my cleanings, our conversations pick up right where we left off. Marna, Rosie & Dr. Thomas are THEE BEST! I’d leave ten stars if I could.”
