Over 30 Years as a Trusted Seattle Dentist

dr dexter barnes seattle dentist“I love being a dentist. From the momen at I decided that dentistry was my calling back in high school, I never changed my mind and never had a moment of regret about my decision.

The driving vision for my entire career has been very simple: offer excellent care while making every dental visit a positive experience and do whatever I can to have a positive effect on the dental profession as a whole. These goals are still the basis for everything we do here at Seattle Dental Associates. I look forward to sharing  a positive dental experience with you and your family.”
