After leaving Mercer Island, I attempted to find another dentist closer to Kent, but I couldn't find one of the same caliber as Dr. Maruhashi. His staff is considerate and friendly. His hygienists do their best to minimize your discomfort and are also very nice. His office is small but pleasant. Finally, the doctor seems very competent.
In addition, when you first sign up to go there, they do not try and force expensive "smile evaluations" or other similar things on you. Unlike many other offices, they don't force expensive and unnecessary dentistry on you.
