The Koehler Mahlstedt Family Foundation concentrates its giving on education, cultural arts, and environmental/conservation causes, with a notable interest in animal welfare. A large proportion of assets flow to a small number of organizations—most prominently United World College USA—while other grants support regional arts institutions and conservation projects, especially in California. Their pattern suggests family-driven priorities that blend support for selective national education programs with local community cultural and environmental initiatives.
The Koehler Mahlstedt Family Foundation shows a clear preference for a small number of repeat recipients, led by United World College USA, which received $50,000 in 2023 and $55,000 in both 2024 and 2025. That repeated support places education at the center of the foundation’s recent activity, while its other grants point to a mix of cultural, environmental, and animal-focused giving. The foundation also backed San Diego Symphony with a $50,000 grant in 2023, indicating support for classical music access for local communities. Alongside those larger awards, it made smaller grants to organizations working in conservation, wildlife care, and animal welfare, including Save the Redwoods, The Living Desert, and several rescue groups. The pattern suggests a family foundation with selective priorities rather than broad dispersal, combining ongoing support for a few institutions with a wider set of local and regional nonprofit partners. Its recent portfolio includes education, performing arts, habitat conservation, and direct animal services.
Education is one of the foundation’s most visible themes. United World College USA received three grants across 2023 to 2025, including two awards of $55,000, showing sustained support for international secondary education. The foundation also funded Saint James School with $25,000 in 2025, after prior grants of $10,000 in both 2023 and 2024. Environmental and conservation work is another recurring area. Save the Redwoods received $25,000 in 2025 and $15,000 in 2024, while Clean Up the Cayes was awarded $20,000 in 2024. Animal-related giving appears in several forms, from $27,000 to San Diego Humane Society in 2025 to $20,000 and $10,000 grants to The Living Desert for desert plants and animal care. The foundation also supported youth shelter services and senior services through smaller local grants.
Grant sizes cluster around modest to mid-sized awards: the p25 is $5,000, the median is $10,000, and the p75 is $23,762. At the top end, the foundation makes repeated larger commitments to selected organizations, while many other awards sit at $5,000 or below. The recent record also shows multi-year support to several recipients rather than one-off gifts; United World College USA, Saint James School, Save the Redwoods, The Living Desert, Southern California Labrador Retriever Rescue, and Eddy House each appear in more than one year. The foundation does not fund individuals and does not make program-related investments.
