Mission & Focus Areas
The foundation’s mission is to improve the life outcomes of its community’s youth by advancing change in the systems that serve them. It awards Stoneleigh Fellowships and Emerging Leader Fellowships to leaders working within or alongside youth-serving systems. Fellowship projects may advance applied research, policy change, or improved practices and services.
The foundation says it prioritizes projects that help systems coordinate, improve service design and delivery, and generate knowledge through action-oriented research. Its stated priorities are youth justice, child welfare, education, and health. Its website also says projects should affect policy or practice for young people in Philadelphia, though it may consider some statewide, regional, or national work affecting Philadelphia youth.
The foundation’s 2025 grants included support for organizations with varied missions. Juvenile Law Center, which received $185,500, describes its mission as fighting for youth rights, dignity, equity, and opportunity and reducing the harms of child welfare and justice systems. Rock to the Future, which received $10,000, says it supports positive youth development and economic empowerment through free, student-driven music programs for Philadelphia youth in under-resourced areas. Health Resources in Action, which received $10,000, says it partners with individuals, organizations, and communities to transform practices, policies, and systems that improve health and advance equity.
Grantmaking
In 2025, the foundation reported 28 grants totaling $2,790,164. Individual grants ranged from $438 to $197,763, with a median of $88,425. Its largest reported grants included $197,763 to Children’s Hospital of Philadelphia for a research fellowship, $188,204 to Philadelphia City Fund for the Philadelphia Police Department, $185,500 to Juvenile Law Center for a research fellowship, and $182,675 to Rutgers University for its Department of Sociology, Anthropology, and Criminal Justice. Other large awards included grants for research fellowships and work associated with the University of Pennsylvania Stuart Weitzman School of Design and the Philadelphia Center for Gun Violence Reporting.
The Stoneleigh Fellowship provides multiyear funding to accomplished leaders. The foundation’s website says fellowships generally run two to three years, with the possibility of extension. A separate program description gives an award range of $200,000–$450,000, with awards of $100,000–$150,000 annually. New Stoneleigh Fellowship submissions are paused effective August 1, 2026.
The Emerging Leader Fellowship is described as a two-year learning opportunity for early-career professionals in Greater Philadelphia. Organizations submit an application form and a two-page project summary; invited organizations submit full proposals and, if approved for the next phase, recruit potential Fellows.
The foundation’s stated Stoneleigh Fellowship criteria include the project’s significance, its potential to promote systems change and improve youth outcomes, and its feasibility. Its eligibility information excludes projects providing direct service to individual beneficiaries, lobbying or advocacy aimed at influencing specific legislation, work that does not affect youth or young adults, and projects carrying out the duties of existing staff.
