“This is the best dentistry in the PNW! Molly at the front desk is so kind and always makes me feel like one of their VIP clients. The dental hygienists are all kind and Doctor Thomas is a straight shooter. Both myself and my Mom visit this office and couldn’t recommend it more!”

“Just a cleaning today. Megan was very good, a professional who is very capable at what she does. Pleasure visiting this dental office.”
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.”

“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.”

“Friendly, casual, and comfortable environment, because of the team of knowledgeable and caring staff, starting with Molly at the front desk!😃”
Madeleine Dow
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.”

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?!!”

“Dr. Jaswal is an absolute pleasure to work with!”
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.”
E. Victoria Simone
Happy Client from Mercer Island Office
“I truly love my dentist and the wonderful staff. I’ve been a patient for almost six years and my visits have all been a good experience. I feel confident and well cared for. Everyone is friendly and very professional. 100% Thank you all!”
