We have been looking for a family dentist who can see the four of us in one block. By great coincidence, we found Dr. Koo in our West Seattle neighborhood. The practice was clean, friendly staff, our kids enjoyed their visit, and I can personally confirm that he was precise and painless when he was working on my teeth. Thank you Dr. Koo and team!
