Matthew Yu, DO, MPH
Associate Program Director

Hector Llenderrozos

Matthew Yu, DO, MPH is an Assistant Professor Director at Charles R. Drew University of Medicine and Science in the Department of Family Medicine. His academic interests include healthcare access, primary care, and health equity. Out of conviction in his faith, Dr. Yu has chosen to live and practice medicine among communities facing social and health inequity. He was inspired by the words of Father Boyle, Founder of Homeboy Industries, who once responded to the question, “How do you work with the poor?” His response: “You don’t. You share your life with the poor. It is as basic as crying together. It is about ‘casting your lot’ before it ever becomes about ‘changing their lot.’”

Driven by this focus, he sought Family Medicine training in the Los Angeles County Harbor-UCLA Medical Center with an area of concentration in community medicine and adolescent health. Later on he stayed on with the safety-net hospital as Chief Resident. After seeing the complications of common chronic medical conditions afflict so many of his patients, he decided to pursue a Master of Public Health from UCLA. Dr. Yu spent time as medical director of North Side Christian Health Center, a federally qualified health center, focusing on increasing access to care for vulnerable populations. He contributed to the Allegheny County Health Department’s establishment of free, accessible Covid-19 testing and care linkage between homeless shelters and community health centers. Since joining CDU and MLK OPC in their service of South Los Angeles, he has invested himself in training the next generation of Family Medicine physician leaders in hopes they will also serve in underserved communities.
