“I was a new patient for best dentistry - I was treated with kindness and Dr. Koo talked me through how to best maintain my dental hygiene by showing me photos and X-rays of my teeth and explaining why certain dental hygiene tasks are important. I immediately trusted his judgement and have found my new regular dentist! Also a great central location for Ballard, Greenwood, and blue ridge neighborhoods.”
