About Me

Dr. Elizabeth Fei-Wen Tsai studied medicine at Western University of Health Sciences in California and went on to complete her residency at St Johns Medical Center in Michigan. She decided to choose a career in medicine because she found the science behind medicine and stories told by each patient intriguing. She also feels a sense of satisfaction seeing patients getting better after treating them. 

What I enjoy most working with patients is making a meaningful impact in their lives by helping them heal and feel whole again. It is important for me to see them healthy and help prepare them for their next step in life.

Dr. Tsai grew up in Southern California and is fluent in English. She also speaks two other languages Taiwanese and Mandarin. Outside of medicine, she enjoys hiking, reading, and trying new food.
