Johnny Tsai

Dr. Johnny Tsai, M.D. is a family medicine physician at Portola Direct Primary Care. He emphasizes a patient‑centered, Direct Primary Care model that limits his panel to a few hundred patients so he can spend ample time listening to each individual's story, often beginning a visit with a relaxed conversation over coffee or tea. Dr. Tsai integrates natural therapies, nutrition counseling, and acupuncture alongside conventional medicine, believing that balanced, holistic care leads to better health outcomes.

Born and raised in Los Angeles, Dr. Tsai is a father of two daughters and enjoys surfing, snowboarding, cooking, and photography in his spare time. He is committed to building long‑term, trusting relationships with his patients, providing same‑day or next‑day appointments, extended visit times, and personalized health‑and‑lifestyle guidance. His approach reflects the core DPC philosophy of reducing unnecessary tests and costs while delivering comprehensive, compassionate primary care.
