The Masserini Maurice J Tua foundation focuses on unrestricted, general operating support for a range of San Diego–area nonprofits providing direct services — especially housing/homelessness initiatives, behavioral health and developmental disability programs, health care providers, and animal-assisted services. Grants are frequently repeated to the same organizations and tend to be mid-sized awards distributed across social service, health, arts, and animal welfare nonprofits. The pattern suggests a local, service-oriented donor who values sustaining core operations rather than project-restricted funding.
A repeated pattern of general operating support defines Masserini Maurice J Tua’s recent grantmaking. The foundation has backed San Diego–area nonprofits across housing, behavioral health, developmental disability services, health care, youth support, and animal assistance, with several organizations appearing more than once across 2023 to 2025. That consistency points to a funder focused on sustaining established service providers rather than isolated projects. Among the clearest examples is Noah Homes Inc in Spring Valley, which received multiple awards, including $20,000 in 2025 and $10,000 in 2024 and 2023. Home Start Incorporated in San Diego also appears repeatedly, with grants of $20,000 in 2023 and $17,000 in 2025, along with a $15,000 award in 2024. These awards sit alongside support for organizations serving related needs, such as San Diego Rescue Mission Inc, Solutions for Change Inc, and Center for Community Solutions. The foundation’s active grant program, the Maurice J. Masserini Trust grantmaking program, is broader in stated scope than the recent grants alone: it supports established 501(c)(3) nonprofits in arts, education, environment and animals, health, human services, and religion, while generally favoring project-specific funding.
Housing and homelessness organizations form a clear part of the foundation’s giving. San Diego Rescue Mission Inc received $15,000 in 2024 for general operating support, while Solutions for Change Inc received $15,000 in 2023 and $10,000 in 2024. Behavioral health and family services are another recurring thread. Center for Community Solutions received $10,000 in 2023, 2024, and 2025, and YWCA of San Diego County received multiple general operating grants, including $10,000 in 2023, 2024, and 2025. Health-related giving includes both direct care and blood services. Sharp Healthcare Foundation received $10,000 in 2024, Scripps Health received $10,000 in 2023, 2024, and 2025, and San Diego Blood Bank received $10,000 in 2025. Animal-focused grants also appear, including $10,000 to Canine Companions for Independence, $10,000 to Rancho Coastal Humane Society, and $10,000 to California Labradors Retrievers and More Rescue.
Typical grants cluster tightly around the middle of the foundation’s range: p25 is $5,000, while the median and p75 are both $10,000. Recent awards also include larger $15,000, $17,000, and $20,000 grants, but most of the listed grants sit at $10,000. The pattern is repeat giving to the same organizations across multiple years, especially in San Diego County. The foundation is a private family-style trust structure rather than a DAF, and it funds organizations rather than individuals. The active program accepts unsolicited applications and is stated to prefer project-specific support, even though the recent grants are largely general operating awards.
