Phillip Coffin, MD, MIA, FACP, FIDSA
Program Medical Director


Dr. Phillip Coffin is a board-certified and practicing internist, infectious disease specialist, and addiction medicine specialist. He has attended or trained at Brown University, Columbia University, the University of California San Francisco, and the University of Washington. He directs the Center on Substance Use and Health at the San Francisco Department of Public Health, where he oversees clinical trials assessing medications for substance use disorders and interventions for opioid safety, overdose prevention, HIV prevention, and Hepatitis C treatment.

Dr. Coffin also conducts studies on the impacts of changing opioid prescribing practices on vulnerable populations, substance use epidemiology, and initiatives addressing substance use and opioid safety in clinical care. To be perfectly candid though, he'd rather be kitesurfing.
