In the aftermath of the Civil War and the epidemics of the 1870s, the Sisters developed a health care ministry, daycare for working mothers, an orphanage and a shelter for elderly women and those seeking employment. They also taught religion and basic education to boys at night.
In 1924, Mercy Hospital opened, and was staffed by the Sisters for the next 70 years. In 1994, it merged with Southern Baptist hospital and was acquired by Tenet Healthcare Corporation.
By the late 1970’s the Sisters established or became involved with a series of outreach ministries in New Orleans. Today, Mercy Family Center, an outpatient behavioral health clinic for adolescents and their families, founded by Sister Sarah Ducey, RSM, still serves the community.
The Sisters continued teaching children at St. Alphonsus until August 2005, when Hurricane Katrina hit. The school served as a temporary shelter for those who didn’t evacuate. It reopened in January 2006 as an early childhood education center.
