Dr. Koo and his assistant were very efficient and thorough and did a great job cleaning my teeth. I am very happy with the service I got and recommend this office to others.

The front desk staff was wonderful! They got me in quickly and was able to help fix my issue, they were also wonderful when I had questions about my insurance coverage. I will definitely recommend Dr. Koo, he was great, kind, and thorough!
