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.”

“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.”

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!”

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.”
Linda Scott
Happy Client from Kirkland Office
“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.”
Ronald Folse
Happy Client from Kirkland Office
“I’vy been a patient with Dr Troy for fifteen years and have always been impressed with him and his entire staff. I am 86 years old and was hesitant to make my visit, but his whole staff used the best practices to insure the safety in the office. Unfortunately , I will be moving to California ima month or so and will have to find a new dentist , and hope that they will be as good as Dr Thomas and his staff.”
