A note from Dr. Thomas
You should never wonder if your dentist is selling you something you don’t need. We’ll tell you what’s actually going on with your tooth, what your options are, and what you can wait on. And if something we did isn’t right, we’ll make it right.

Happy Client from Mercer Island Office
“Love the care, personnel and extra special treatment I receive with every visit. Best dentist I have ever had!”
Holly Yee
Happy Client from Kirkland Office
“Such a wonderful dentist's office! The staff is always welcoming, efficient, and they do a great job with my oral care. The other day I had a tooth brush bristle stuck in between two of my teeth and needed to come in for a minute visit. They got me in that day and were able to remove the bristle. It was such a relief! Going to the dentist can somethings be uncomfortable, but at Thomas Dentistry I always feel taken care of.”

“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.”
Nicholas Smith
Happy Client from Kirkland Office
“Clean, friendly, and on time. Their staff took very good care of my teeth and were always very pleasant. Definitely recommend Thomas Dentistry!”
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.”

Happy Client from Mercer Island Office

“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!!!”

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.”
Sarah Gielgens
Happy Client from Kirkland Office
“I have been a patient at Thomas dentistry for over 10 years and have always appreciated their open and friendly atmosphere, knowledgeable and helpful advice, use of new technology and methods, consistent and kind care. Dr. Thomas, Dr. Nguyen, and Dr. Jaswal have all demonstrated genuine care and interest in their patient’s lives, dental health and history, and other medical concerns. I admire their dedication to providing excellent solutions to dental problems, and patience with special issues. I would recommend this team to everyone!”
