I think Dr Koo and his staff does a wonderful job! I feel like they take their time to listen attentively and answer all questions and concerns thoroughly. There was very little waiting, even to get a walk-in blood draw. I was very impressed.

I always feel so welcome by everyone in the office - from the front desk to the nurses and doctor.
