“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.”

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.”

“First visit back to the dentist in awhile after not having insurance. Everyone was very welcoming and informed. Cleaning was very efficient and information was communicated clearly Thank you Dr. Zou, Kathy, Carmen, and Nicole! I'll definitely be coming back for further dental care.”
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.”
William Kit
Happy Client from Kirkland Office
“Friendly, Highly Skilled and the Staff explain every detail of procedures needing to be done including Billing Pricing. I Highly recommend Thomas Dentistry!!”
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.”
Audra Saisslin
Happy Client from Mercer Island Office
