The May Foundation Trust concentrates its modest giving into a small number of sizable, repeat grants to mission-driven nonprofits, with a clear emphasis on animal welfare and local community services. Its highest-dollar recipients are specialized rescue organizations (wildlife and horses) alongside at least one child-welfare/education nonprofit, suggesting interest in hands-on care and direct service delivery rather than broad institutional philanthropy. Grants are few but sizable and often repeated to the same organizations, indicating long-term relationships with select grantees.
The May Foundation Trust’s recent giving is dominated by repeat support for a small set of animal-welfare and direct-service nonprofits, with $50,000 awards going to Wildlife Rescue of Napa Valley and Sunrise Horse Rescue in 2024. That pattern continues into 2025, when both organizations received follow-on grants, showing a relationship-based approach rather than one-off gifts. The foundation also backs a child-welfare and education organization, The Resource Foundation, which received one of the largest grants in the record and returned for additional support the following year. Across the recent grants list, the trust’s giving centers on hands-on care: rescue, rehabilitation, and local service delivery. Smaller awards extend that same preference into related work, including wildlife care, equine rescue, and community-facing support. The recipient list also shows occasional grants to advocacy and reproductive-health groups, but those are a smaller part of the overall pattern. With annual grants totaling $485,500 and a typical gift size in the low-thousands, the trust uses comparatively few grants to support a narrow group of organizations over multiple years.
Animal welfare is the clearest theme in the trust’s grant record. It gave $10,000 in 2024 and $10,000 in 2025 to Ventana Wildlife Society in Monterey, and it also supported Muttville Senior Dog Rescue with $10,000 in 2024. Equine rescue appears as a separate strand: Sunrise Horse Rescue received $50,000 in 2024 and $30,000 in 2025. Wildlife rehabilitation is another recurring area, with Native Songbird Care & Conservation receiving $5,000 in both 2024 and 2025. Beyond animal care, the trust supports education and child welfare through The Resource Foundation, which received $30,000 in 2025 after a $50,000 grant in 2024.
Typical grant size is concentrated in the low-thousands: the p25 is $2,000, the median is $4,000, and the p75 is $5,000. Even with that distribution, the trust also makes a smaller number of much larger awards, which points to a tiered pattern rather than uniform grants. Several recipients appear across multiple years, including Wildlife Rescue of Napa Valley, Sunrise Horse Rescue, The Resource Foundation, and Ventana Wildlife Society, indicating repeat support. The foundation is a trust rather than a public grantmaker, and it does not fund individuals or make program-related investments.
