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!”

“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!”

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.”

“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.”

Happy Client from Mercer Island Office
“I have been a patient of Dr. Thomas since he began his practice. He is thorough in his exams, and professional in his treatments. He has done root canals, implants, and crowns for me, and the results have always been very good.”
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.”
Zach Kelly
Happy Client from Kirkland Office
“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.”

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.”

“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.”
