The Arlene and Michael Rosen Foundation concentrates its giving on direct health and social services for people experiencing homelessness, substance use disorder recovery, and community-based primary care in California. Grants are large, often flexible or general operating awards that support program expansion (street health/mobile clinics) and staffing. The foundation favors a small number of repeat grantees and place-based initiatives that deliver frontline care and peer-based supports.
The Arlene and Michael Rosen Foundation’s largest recent grants center on street health and mobile care for people experiencing homelessness, especially in California communities. A $754,728 award to Community Through Hope supported street health program expansion in Chula Vista, followed by a $505,000 grant for South Bay street medicine core operating support. That pattern matches the foundation’s broader emphasis on frontline care, where funding often covers staffing, operating capacity, and program expansion rather than narrow project-only awards. The foundation also backs organizations that connect health care, outreach, and recovery services. Father Joe’s Villages received $300,000 for street health program expansion, and Mendonoma Health Alliance received $225,000 for a mobile medical clinic program, paramedic clinic staffing costs, and community health worker staffing. Other grants support community-based primary care, harm reduction, peer support, and behavioral health. Across the recent grants list, repeat awards appear frequently, with several organizations receiving support in more than one year. The overall picture is of a California-centered funder that favors direct service providers, flexible support, and practical funding for clinics, outreach teams, and community health infrastructure.
Street medicine is a major theme in the foundation’s giving. Community Through Hope received $754,728 for street health program expansion and $505,000 for South Bay street medicine core operating support, while Father Joe’s Villages received $300,000 for street health program expansion. Mobile and community-based clinical care is another visible area. Mendonoma Health Alliance was awarded $225,000 for a mobile medical clinic program, paramedic clinic staffing costs, and community health worker staffing, and Lifelong Medical received $200,000 for the Alameda Wellness Campus. The foundation also supports harm reduction and recovery-oriented services. Mendocino Coast Hospitality Center received $112,000 for flexible harm reduction funding and $106,000 for outreach specialist and new harm reduction services, while Aloha House received $30,000 for a Maui fires emergency grant. Veterans and peer-based healing appear as well: Caron Foundation received $100,000 for veterans healing through connection workshops.
