Sam Lee, MD
Sam Lee, M.D. was born in Flushing, NY but grew up in Kyrgyzstan most of his life and calls the Tian Shan mountain range his home. He is a proud Notre Dame grad, where he studied sociology and solidified a lifelong dedication to social justice. He spent two years working with refugee communities both in the U.S. and abroad, before heading to Eastern Virginia Medical School where he further developed his love for primary care. After completing his Internal Medicine residency in the UCSF San Francisco General Primary Care Track, Sam is excited to explore the intersection of substance use disorders and adolescents, individuals that identify with gender minorities, and people living with HIV. He plans a career practicing primary care in urban underserved communities—wherever that might lead him. When not practicing medicine, Sam can usually be found stanning Bangtan, sorting people into their respective Hogwarts houses, running in Chrissy Field, or proselytizing Californians about public transportation.
