Stoneleigh Foundation
At a glance
Key takeaways
- If your work falls within youth justice, child welfare, education or health and is based in the Philadelphia area, the foundation's stated focus fits, and its Emerging Leader Fellowship, where eligible hosts include academic institutions, nonprofit organisations and public-sector agencies, is the clearest route in.
- Half of its grants to organisations were $50,000 or less and the median was $50,000, so a modest request is realistic; about 8 in 10 of its grants fall between $7,650 and $190,000, a typical band rather than a ceiling, and its largest was about $320,000.
- In its most recent filing, 64% of its grant dollars to organisations went to groups it had funded in earlier filings, so it leans toward repeat grantees, though a first approach remains open.
- Apply by submitting an application form and Letter of Interest within the scheduled window, with realistic goals achievable within two years, a clear approach to tracking impact and young people engaged as active participants.
- Do not apply for Fellowship projects focused on lobbying or advocacy aimed at specific legislation or political campaigns, or for projects that focus exclusively on direct services to individuals.

What they fund

Priority Areas
The Foundation awards Fellowships to exceptional individuals who work within and alongside youth-serving systems. Its priorities are youth justice, child welfare, education and health, and it seeks to improve young people’s life outcomes by advancing change in those systems. Its Fellowships support work that strengthens coordination, improves practice and generates new knowledge through action-oriented research. For the Emerging Leader Fellowship, eligible hosts include academic institutions, nonprofit organisations and public-sector agencies. The Foundation seeks proposals that address a well-defined, unmet or under-resourced need as defined or demonstrated by the community served, and values approaches that engage young people as active participants or create conditions for them to flourish. It also cultivates leadership and collaboration among Fellows.
