Chelsey Swan
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.”
Milo
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.”
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.”
Alejandro
Happy Client from Mercer Island Office
“I can't recommend this practice enough. Everyone who works here is courteous, professional and extremely competent. 10/10”
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.”
Jacqueline Roer
Happy Client from Mercer Island Office
“Five stars! Great Dentist and work he does and great staff.”
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.”
Henry Pang
Happy Client from Mercer Island Office
“The services are great and very professional.”
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!”
