About St. Mary's Medical Center


St. Mary's Medical Center, founded and sponsored by the Sisters of Mercy and part of the Dignity Health System, has cared for the people of the San Francisco Bay Area since 1857. Today, Dignity Health is the largest not-for-profit, community-based health care provider in California.

“Of all the forms of inequality, injustice in healthcare is the most shocking and inhumane”
  - Martin Luther King

St. Mary's partners with more than 150 academic and community hospitals across the country as a member of Common Spirit Health, the largest national network of not-for-profit medical centers dedicated to health equity, state-of-the art care of our most vulnerable populations, and a resident, faculty and allied professions workforce which mirrors the tremendous racial, ethnic, cultural and gender diversity of our patients.  St. Mary's is the original flagship hospital for the health system, whose headquarters remains in San Francisco. Our Common Spirit CEO, Lloyd Dean, was a prominent advisor to the Obama administration during the inception of the Affordable Care Actand is widely recognized as one of the most influential health care executives in the United States.  With the powerful support of our Common Spirit leadership, the St. Mary's Internal Medicine residency program is passionately dedicated to social justice, inclusion, and diversity with the foundational vision that social justice has everything to do with healthcare.

We believe in our city. We started health care in San Francisco. And are as committed today as we were in 1857. Through charity, advocacy, and compassion, we want to spread human kindness beyond our hospital walls.
