Marissa A. Boeck, M.D., M.P.H. is an Assistant Professor in the Department of Surgery, and serves as an acute care surgeon at Parnassus and as an acute care and trauma surgeon and surgical critical care intensivist at Zuckerberg San Francisco General Hospital (ZSFG). She is a Co-Director of the Center for Health Equity in Surgery and Anesthesia (CHESA), as well as the Director of General Surgery/Trauma within the Center and is a member of the WHO Collaborating Centre for Emergency and Trauma Care. She has a B.A. in Philosophy from the Macaulay Honors College at Hunter College, and received her M.D. from Weill Cornell Medical College in 2011. Dr. Boeck completed her general surgical residency training at NewYork-Presbyterian Hospital/Columbia in 2018, during which time she obtained a Master of Public Health degree from the Johns Hopkins Bloomberg School of Public Health in the first of two research years away from clinical duties. The second was spent in Santa Cruz, Bolivia working on hospital-based trauma registry implementation, and developing the city's trauma and emergency response system.

Dr. Boeck's professional passions center around global public health, especially as it relates to injury prevention (road traffic, firearm-related violence), vulnerable and marginalized populations, emergency response, and trauma and surgical system strengthening in low-resource environments. She also focuses on exploring trauma survivorship with a core focus on and inclusion of patients and communities, determining how best to ensure our patients not only survive but thrive after their initial injuries. She champions diversity in the surgical workforce, and the power of social media in medicine and research. Her research spans both domestic in California and the United States and abroad across multiple countries including Bolivia, Kenya, Cameroon, and Tanzania.
