The Seybert Foundation is dedicated to providing support to nonprofit organizations serving disadvantaged children and youth in the City of Philadelphia. The foundation focuses on:
- Education (elementary and secondary education, early childhood education, child educational development)
- Child welfare and child development
- Human services and family services
- Support for economically disadvantaged and low-income individuals
The foundation prioritizes addressing current trends affecting Philadelphia's children, including safety and violence/trauma, incarceration and its effects, physical and mental health, reduction of services and opportunities in public schools, and changing demographics of the city.
Grantmaking
In 2013, the Board voted to make all grants in the form of General Operating Support, recognizing the scarcity of this type of funding for nonprofits. The foundation actively encourages other funders to consider providing general operating support.
