Dr Tsai is the rare MD who takes time with you, interviews you himself so you don’t need to fill out a million forms and calls you back himself to discuss test results. Very accessible and compassionate. Highly recommend Dr William Tsai!

Dr. Tsai is a very compassionate doctor who spends time with you and is truly concerned about your health. He is treating me for high blood pressure and doesn't make me wait one to four months after prescribing a different pill. I am so glad I found this doctor.

Dr Tsai is a the best primary care doctor. My husband has chronic medical conditions requiring consultion between several Hoag doctors and City of Hope. Dr Tsai communicates clearly and responds to our calls on the same day. Most importantly, my husband trusts and feels the doctor listens to him! office staff is very responsive to our request for Appts when he is ill. I am grateful we have Dr Tsai on my husband’s medical team

Dr. Tsai came to see my mom in the ER and then everyday that she was in the hospital. It was great to see her regular doctor instead of a hospitalist. It made her feel comfortable.
