The Ayrshire Foundation concentrates its giving on local Southern California causes — especially Pasadena and nearby coastal communities — funding land preservation, civic park/watershed projects, homelessness and housing services, and local cultural institutions. Grants tend to be general support and sizable, often repeated to the same organizations, suggesting long-term partnerships with place-based nonprofits rather than one-off national grants.
The Ayrshire Foundation’s recent giving is anchored by repeated, large grants to place-based organizations in Southern California, especially in Pasadena and the surrounding Los Angeles region. Three separate $250,000 grants to PV Land Conservancy across 2023 and 2024 point to an ongoing commitment to coastal and open-space protection in the Palos Verdes area. The foundation also made major support grants to Union Station Homeless Services, including $175,000 in 2023 and $100,000 in both 2024 and 2024 again, showing a sustained relationship with one of Pasadena’s core homelessness providers. Its grant record also includes general support for local civic and cultural institutions such as Southern California Public Radio, Pasadena Conservatory of Music, One Arroyo Foundation, and Keck Medicine of USC. Those awards sit alongside grants to health, housing, animal welfare, and community service organizations, indicating a portfolio built around institutions residents encounter in daily life. The pattern is place-based rather than national, with most awards going to California recipients and many to Pasadena-based nonprofits.
Environmental and land-conservation work appears as a major thread in the foundation’s giving. In 2023 and 2024, it awarded three $250,000 grants to PV Land Conservancy for general support, signaling repeated backing for coastal and open-space protection in the Palos Verdes area. Another place-based civic project received $100,000 in 2025: One Arroyo Foundation for general support, tying the foundation to local watershed and arroyo restoration work. Housing and homelessness services are another clear area of support. Union Station Homeless Services received $175,000 in 2023 and additional $100,000 grants in 2024, all listed as general support. Community health and care also show up in the record, including $100,000 to Sycamores in 2025 for general support and $75,000 to The Gooden Center in 2024. The foundation’s arts and media giving includes $137,500 to Southern California Public Radio and $100,000 to Pasadena Conservatory of Music.
The Ayrshire Foundation’s typical grant size is mid-to-large: the 25th percentile is $3,750, the median is $22,000, and the 75th percentile is $56,250. The recent record shows many general-support grants, with several organizations receiving multiple awards across years, which points to recurring relationships rather than one-time gifts. Its work is through a foundation structure, not individual giving or program-related investments. The overall pattern is geographically concentrated, with most grants going to California recipients and many to the same Pasadena-area nonprofits.
