      Between myself and family, I have met many doctors over the years at UCSF. In my opinion Dr Chan Tack is one of the best Doctors at UCSF she listens, she cares, she explains, she is very intelligent and she can think. You know she loves her job. I am very happy to have her as my doctor.

      Dr. Tack Chan is very thorough and professional. I would recommend her to others as a primary care provider.

    Please check with your health insurance plan regarding coverage for this type of care. Not all providers at UCSF Health are covered by every insurance plan.
