Sue Dwyer
Happy Client from Kirkland Office“Great experience with hygienist today. Thank you for being so kind and not judgemental. Looking forward to a long relationship with this dental office.”
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.”

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.”

Vanessa Hoffman
Happy Client from Kirkland Office“This was my first dental visit and I must say they were definitely unorganized as their X-ray machine kept freezing the images delaying my appointment and they’re not put together. The manager Carmen told me I was going to have to pay a $70 balance. Which I completely agreed on no problem. I got a bill for $140 and was never told I had a $50 co-pay on top & they don’t use silver filling so I had to pay extra for a white filling. I was not told about any of these extra charges. The manager Carmen hung up on me over the phone without trying to fully explain everything and was very rude to me. I would not recommend this dentist because they are not truthful and they want you to pay double your bill so please be careful.”

Happy Client from Mercer Island Office“Professional, friendly and patient centered care. My first visit and I am thoroughly impressed. Great office culture and staff love what they do and it shows. Thank you.”
Tyler D
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.”
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.”
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 !”
