Our Providers

Dr. Ming Li Tsang

My desire to become a physician began at an early age when I was still living in China. My mother was working in a hospital; she would take me to work with her and the hospital became my playground.  I saw so many patients suffering from pains and injuries and these experiences had a profound effect on me: I wished that someday I, too, would be able to help the sick and injured.

Dr. Ekkawit Chanchorn

I am a primary care physician serving the San Francisco Bay Area. I was born in Thailand and speak fluently in both Thai and English. In 2005, I received my Doctor of Medicine degree from Chiang Mai University. Thereafter, I received my Ph.D. in the Chemical Biology Interdisciplinary Program at the University of Houston and won the Employee recognition award for outstanding scientific productivity in 2009.
