“Dr. Thomas and his team have managed my dental care for over a decade and I couldn't be happier with how I've been treated. Highly recommend coming in to see him for anyone in need of dental care.”

“Cathy did an amazing job cleaning my teeth! She was informative on what is going on in my mouth! Looking forward to my next cleaning!”
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.”
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.”

“Thomas Dentistry makes going to the dentist something to look forward to.”
Susan Slagle
Happy Client from Kirkland Office
“I just recently transferred over to Thomas Dentistry and I’ve had two appointments so far, which I have had positive experiences with. The front desk is very friendly and accommodating, and they let you know about costs up front. I’ve had two different hygienists and they both have been good and thorough. I saw Dr. Jaswal both times and he has a very calm demeanor which puts you at ease. He also has a good sense of humor. Thomas Dentistry takes the unpleasantness out of going to the dentist!”

“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.”
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.”
Tyler D
Happy Client from Mercer Island Office
“I just started going here this year after bouncing around different dentist for years and have had a great experience each visit. I have had everything from cleaning, fillings, root canal, crown and they have all gone well. The office is nice, conveniently located and has off street parking. The entire staff is very friendly and helpful. Dr. Jaswal is excellent, takes his time not only with his work but explaining what you have going on, your options etc. Overall only good things to say about this place and definitely recommend it.”
