Dignity Health began as a single hospital founded on the belief that all people deserve medical care, regardless of their background, ethnicity, or circumstances. The Sisters of Mercy, originally founded by Catherine McAuley in Dublin, Ireland in 1831, vowed to serve people who suffer from poverty, sickness, and lack of education. In 1854, eight Sisters arrived in San Francisco, California and immediately began caring for residents of a city struck by cholera, then typhoid and influenza. They founded St. Mary's Hospital, now the oldest continuously operating hospital in the city. Today, Dignity Health is one of the largest health systems in the nation with 400 care sites across a 22-state network, including 39 hospitals -- 24 of which are Catholic and 15 are other-than-Catholic. The mission and values we were founded upon remain the same. Through teamwork and innovation, faith and compassion, advocacy and action, we endeavor every day to keep our patients happy, healthy, and whole. Hello humankindness.
