About William Jeff and Jennifer Gross Fam
The William Jeff and Jennifer Gross Fam gives at a scale that includes repeated $3,000,000 general donations to Doctors Without Borders, alongside major support for Mercy Ships and hospital-based care organizations. The pattern points to large, unrestricted gifts for medical humanitarian work, emergency relief, and healthcare delivery rather than narrowly earmarked project funding. Recent grants also show a strong hospital and children’s-health component, with substantial awards to Atrium Health Foundation and Choc Foundation. The foundation’s giving also reaches beyond direct care into the institutions and public-interest organizations that surround it. In the recent-grants list, the family backed university, community, and arts-related recipients such as University of Massachusetts Foundation Inc, Environmental Media Association, and Orange County Teachers of the Year. Across those gifts, the grant language is typically “general donation,” which suggests support for organizational use rather than a single program. The overall picture is of a funder that uses sizable discretionary grants to support established nonprofits in health, humanitarian relief, education, and selected arts and civic roles.
