    Dr. Tsao was exceptional! She listened to all my concerns and addressed all the questions I had and was very polite. She also referred me to a dermatologist within the UCSF network for a patch test so I could try to further understand what caused my eczema flare up. In addition I had concerns about billing and she offered to write a letter stating medical necessity if my insurance denied my claim.
