My husband and myself used dr. Quan for years until we had to move out of the area. Wish I could have taken him with us. Never an alarmist, never refused a visit if booked, fun to talk to, and he was always giving us top health care. Comforting man. Also his staff was wonderful to us.

Dr Quan saw my family member on very short notice when he experienced unexplainable shortness of breath when exercising. To be perfectly accurate, there were no follow-up visits, but I couldn't have asked for better care than we got from this office. Dr Quan clearly cares about his patients.

This man should not be allowed to call himself a doctor. Shame on him.

I love Dr. Quan. He makes you feel comforted, gets right to the problem. If he can't figure it out, he sends you to a specialist. Can't get better then that. He's not a no it all doctor. I would recommend him nighly
