Amber Lin MD

Program Director

As an eight-year-old, Dr. Amber Lin heard about people in Africa dying from easily treated diseases and decided to become a doctor in order to help. Dr. Lin chose to specialize in Family Medicine during her medical school OB/Gyn rotation when she discovered the joy and challenge of treating both babies and adults. “No two days are similar,” Dr. Lin explains. “As a Family Medicine practitioner, I can get to know an entire family as if they’re my own.” Dr. Lin has an interest in Tropical Medicine and Global Health. She loves music, singing and hip-hop dance.

Warren Woo MD

Family Medicine

Dr. Warren Woo initial motivation to study medicine came from three areas of interest: the challenge of advancing medical science, the complexity of human beings and their systems, and the relational aspect of caring for patients. During his childhood, Dr. Woo experienced kindness and compassion from his own family physician, and this made an impact upon him in choosing to specialize in family practice. He most enjoys hearing from a patient that “what we did for them changed their life.” He also enjoys helping to give patients more quality years to enjoy time with their family and significant events in their lives through improved healthcare. Prior to beginning medical school, Dr. Woo gained life experience as a grocery store clerk, a door-to-door salesperson selling cookware, and a math tutor, chemistry assistant and summer camp counselor while in college. Prior to starting medical school, he worked as a tennis pro.
