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.”

Happy Client from Mercer Island Office“I love coming here & I’m always greeted with smiles. It truly makes me feel great that the staff remembers my name & even though I visit every six months for my cleanings, our conversations pick up right where we left off. Marna, Rosie & Dr. Thomas are THEE BEST! I’d leave ten stars if I could.”

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.”

Happy Client from Kirkland Office“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.”
Barb Patterson
Happy Client from Mercer Island Office“I needed a dentist close to home and they are close enough for me to walk. I've been twice now and both times had a great experience. Dr. Jaswal has a wonderful chair-side manner and super sense of humor.”
Theresa Gehrig
Happy Client from Mercer Island Office“I have plenty of anxieties about getting dental work done and Dr Thomas and his team are understanding and reassuring. His office is so helpful and professional in getting the work done and I have a great deal of confidence in him and his team. Their equipment and materials are up to date. I’m grateful !”

Happy Client from Kirkland Office“Had my teeth cleaned today again by Rosie. She is an excellent Dental hygienist. Takes the time to answer all my questions and is very informative. Greatly appreciate it.”
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.”
