Our History

Mercy was founded as a healthcare ministry of the Sisters of Mercy who have been providing health care in Philadelphia for more than 100 years. The Sisters of Mercy were founded in 1831 in Dublin, Ireland by Catherine McAuley, an heiress who used her inheritance to serve the poor, especially women and children. In Catherine's House of Mercy, Sisters of Mercy cared for the poor, sick and uneducated.

Sisters of MercyBefore she died in 1841, Catherine established 12 Mercy foundations throughout Ireland and two in England, the first convents to be built in that country following the Protestant Reformation. The Sisters of Mercy arrived in Philadelphia in 1861 and immediately began visiting the sick in their homes and setting up schools for the instruction and care of children and adults. The Sisters of Mercy founded Misericordia Hospital (now known as Mercy Philadelphia) in 1918.

Today, there are some 10,000 Sisters of Mercy throughout the world. The Mid-Atlantic Community of the Sisters of Mercy is located in the Philadelphia area.

The hospitals of Mercy Health System became part of Trinity Health Mid-Atlantic in 2019.

Mercy honors its heritage through its vision. As a mission-driven regional health ministry, we will become the recognized leader in improving the health of our communities and each person we serve. We will be known as the most trusted health partner for life.

"In the care of the sick, have great tenderness in all things."
Catherine McAuley
