I’ve been going to Dr. Tang for many years. He is a very busy doctor. I need to booked my appointment 1 – 2 weeks ahead to see him. He is not only certified as a family doctor. He is also a DERMATOLOGISTS, beauty care as Foto facial. He is very friendly and very professional. You need to get to know him. Now as I am a member of Kaiser Permanente. But I still go to see him, because my co-pay is expansive.
