The Slootman Family Foundation makes a small number of very large, project-focused grants across conservation, healthcare and philanthropic institutions. Their giving is concentrated on capital and expansion projects (e.g., land protection and building medical campuses) and they show repeat, multi-year support for select organizations rather than broad, small-dollar giving.
Concentrated, high-dollar grants to a handful of recipients; repeat multi-grant support for flagship causes; primarily capital/project funding rather than many small operational grants.
A defining feature of the Slootman Family Foundation is its concentration on a few very large, project-focused grants. In 2025, it gave $3.2 million to Washington Hospital Healthcare Foundation for general support and $2.5 million to Chileno Bay Foundation Inc for building the children’s medical campus, showing a pattern of backing major health infrastructure rather than broad small-dollar programs. The foundation also extended multi-year support to American Prairie Foundation, with grants of $1.5 million in 2024, $1.5 million in 2025, and $1 million in 2023, all for general support. That repeated funding points to sustained interest in large-scale land and conservation work. Its recent grant history also includes a $100,000 disaster-response grant to Direct Relief for wildfire response in Maui, adding emergency relief to a portfolio centered on institutions and capital projects. Overall, the foundation gives a small number of grants, usually at seven-figure levels, and favors organizations undertaking large, concrete builds or expansion efforts.
The foundation supports pediatric healthcare infrastructure through large capital-oriented grants. It gave $2.5 million to Chileno Bay Foundation Inc for building the children’s medical campus, indicating direct support for facility development tied to children’s health services. It also backed hospital-system work with $3.2 million to Washington Hospital Healthcare Foundation for general support. Conservation is another clear area of giving: American Prairie Foundation received $1.5 million in 2024, $1.5 million in 2025, and $1 million in 2023, all for general support. The grant record also shows disaster response, with $100,000 to Direct Relief for wildfire response in Maui. Across these areas, the foundation appears to fund large projects, institutional needs, and emergency relief.
Typical grant size is large: the distribution shows a 25th percentile of $550,000, a median of $1,000,000, and a 75th percentile of $1,250,000. The recent record also includes multi-year support, especially for American Prairie Foundation across 2023, 2024, and 2025, alongside single grants to other recipients. The foundation is a private family foundation and does not fund individuals. Its grants are concentrated in a small number of awards rather than many small ones, and the recent record suggests discretionary support without an application process described in the data.
