    Dr Tsai was extremely patient, knowledgeable, professional, he thinks broadly and holistically, which I really appreciate. Great expertise as well

    It is rare for a physician to ask if there is anything they would like for me to share that wasn't covered. I felt like the physician cared about my issue and wanted me to get better holistically
