Mercy is a not-for-profit Catholic health care organization located in the Midwestern United States with headquarters in St. Louis, Missouri. It is the sixth largest Catholic health care system in the United States. Mercy was founded in 1871 by Sisters of Mercy as part of the communal support and developed as part of their mission. Currently Mercy serves communities across four states with 32 hospitals and 300 outpatient facilities. Mercy employs 39,000 employees and 2,000 physicians.HistoryThe mission of Mercy comes from the teachings of Catherine McAuley, an Irish nun who founded The Sisters of Mercy in 1831. Mercy in the United States traces its roots to New York in 1846. In 1856 the Sisters of Mercy came to St. Louis and founded the Religious Sisters of Mercy of the St. Louis Province. Fifteen years later, in 1871, they opened a 25-bed infirmary for women and children. Over the years, the Sisters of Mercy expanded their health ministry in the Regional Community’s seven-state area: Arkansas, Kansas, Louisiana, Mississippi, Missouri, Oklahoma and Texas.While the hospitals and other health care facilities sponsored by the Sisters of Mercy were not formally linked, as early as the 1960s they shared management and consulting staff resources.In 1986, to position the individual hospitals for coming changes in health care, the Sisters of Mercy created the Sisters of Mercy Health System.In 2011, Sisters of Mercy Health System renamed many of its hospitals and clinics under a singular brand - Mercy. Hospitals and clinics that use to be familiar as "St. John's Regional Heath center" are now named "Mercy Hosptical Springfield" (Mercy - Entity - Location).
