In July of 1946 the Sisters of Charity of Nazareth, Kentucky purchased what was then called Pennington General Hospital in London, Kentucky and assumed its leadership. Renamed Marymount – Our Lady of the Mountain, the mission of the sisters was to extend the healing ministry of Christ bringing quality health care to the poor and underserved of rural Kentucky. In 1997 Marymount along with seven other Kentucky facilities, became part of Catholic Health Initiatives (CHI) and in 2008 those same eight facilities formed Saint Joseph Health System. At that time the hospital name was changed to Saint Joseph London. An 18-member volunteer board of directors governs CHI Saint Joseph Health, its facilities and operations, including Saint Joseph London with this mission:
The mission of Catholic Health Initiatives is to nurture the healing ministry of the Church, supported by education and research. Fidelity to the Gospel urges us to emphasize human dignity and social justice as we create healthier communities.
As a ministry of the Catholic Church, we will lead the transformation of health care to achieve optimal health and well-being for the individuals and communities we serve, especially those that are poor and vulnerable.
