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.”

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.”

“Had such an amazing experience, and I would highly recommend coming here. I was incredibly thankful especially for how helpful and sweet Marna was. I typically do not like going to the dentist but she made me feel very comfortable and did a wonderful job! Will be back here soon!”

“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.”

“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.”

“First visit back to the dentist in awhile after not having insurance. Everyone was very welcoming and informed. Cleaning was very efficient and information was communicated clearly Thank you Dr. Zou, Kathy, Carmen, and Nicole! I'll definitely be coming back for further dental care.”
Faith Hutcherson
Happy Client from Kirkland Office
“Really enjoyed my experience here for a teeth whitening. The Kirkland location is great; it’s close to the freeway so it’s easy to find, and there was designated parking for patients. The staff (I’m talking from front desk to assistants to the doctor) were all very friendly and extremely efficient. I was talked through what they were doing so I felt at ease the entire time.”
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.”
Megan Cosgrove
Happy Client from Mercer Island Office
“This is the best dentistry in the PNW! Molly at the front desk is so kind and always makes me feel like one of their VIP clients. The dental hygienists are all kind and Doctor Thomas is a straight shooter. Both myself and my Mom visit this office and couldn’t recommend it more!”
