History Bon Secours Mercy Health traces its roots to three founding sponsors, the Sisters of Bon Secours, the Sisters of Mercy and the Sisters of the Humility of Mary.
In 1858 the Sisters of the Humility of Mary was established in Dommartin-sous-Amance, France and came to the US at the invitation of Bishop Amadeus Rapp of Cleveland in 1864. The community grew, building schools and hospitals, serving parishes and meeting the needs of the poor.
In 1881, the Sisters of Bon Secours came to the United States from France to establish a health care ministry in Baltimore, Maryland. After years of providing home health, orphanages, day cares and other public services, the Sisters opened their first hospital in Baltimore in 1919.
Founded in 1931, the Sisters of Mercy arrived in the United States from Ireland at the invitation of the Bishop of Pittsburgh. They focused on caring for the sick and vulnerable, establishing hospitals throughout the United States.
In 2018, offshoots of these three organizations - the Marriottsville, Maryland-based Bon Secours Health System and the Cincinnati-based Mercy Health merged. At the time of the merger, Bon Secours Mercy Health comprised 43 hospitals in seven states and more than 2,100 physicians.
In April 2019, Bon Secours Mercy Health acquired Bon Secours Health System Ireland, creating a system with more than 60,000 employees.
