Founded in 1817, Ralston Center was Philadelphia’s first home for aging women and single women who had fallen on hard times and later evolved to serve the health and wellness needs of seniors in West and Northwest Philadelphia. In the latter decades of the 20th century, Ralston leased its historic building to the University of Pennsylvania’s Institute on Aging, Penn’s Geriatric Medicine practice, and other related geriatric research programs, focusing on public wellness programs and supportive services for older adults in West and Northwest Philadelphia.

Its public programs went virtual during the 2020 pandemic. In 2023, the Ralston House property was sold, and Ralston Center relaunched as the Sarah Ralston Foundation. The Sarah Ralston Foundation is a grantmaker and community partner to organizations serving older adults in Philadelphia.
