    I got royal treatment to the degree that monarchs & presidents...wish they too were her patient -- if they knew who doctor doctor Chan Tack is ( it surely fulfilled the Persian translation of Tack = peerless, one of a kind...) And if she had been my doctor 40 years ago, I honestly can swear I would have been healthier now.

    I need a comprehensive work-up for whatever is going on with my pain. This doctor was good but no one is trying to come up with a plan that would lead to a diagnosis and a course of treatment.

    Since the very first day I met Dr. Chan Tack, she impressed me and knew she was a doctor that really cared about me and my well being. When she moved from Mission Bay, she proposed referring me to another doctor, but I wanted to remain a patient under her care, wherever she went I wanted to follow no matter how far from my home it was. Not easy to find a doctor like Dr. Chan Tack, one that really listens to your concerns and treats me with the utmost dignity and respect.
