Look Your Best

Compassionate dental professionals committed to providing quality care in a relaxing atmosphere.


I have been a patient at Dr. Newton's practice since it started around 20 years ago. The dental service that I have received over that time has been friendly, efficient, effective, and very much appreciated. It has never occurred to me to look elsewhere. A+++

I've been a patient of Dr. Newton's for 16+ years. All of her associates are outstanding. Office is state of the art, as they can fit and make crowns in a single visit. I had an ongoing problem with a root canal that was improperly completed years ago. Dr. Widner played "detective" and solve this ongoing problem! I am very grateful! So pleased with this dental group and would recommend Dr. Rhonda Newton and her associates to everyone!

Good treatment with short waitingroom time and not "booked up" weeks out, like my general Physician

Clearly a superior dental office with superior talent. I've been going to Dr Newton's for over 2 years. I'm turning 55 this year and I've been to my share of dentists in my life -- she is way above the rest. Great personality, very competent, and all the staff I've encountered there are very friendly and skilled. I couldn't ask for a better dental experience and I'll never change offices again. I had to get two crowns in one appointment and I've never had something like that done so quickly and without incident. They have some mileage on them now as they were done a year ago, and they still feel and look great. You're crazy if you live in the Sammamish area and you go anywhere else.
