## About

The foundation was established in 2001 in Scottsdale, Virginia, by attorney Allan B. Winston, who serves as President and Director. The Winston family governs the entity directly: Diana B. Winston holds the Secretary and Treasurer roles, while Julia Winston and Joshua Winston serve as additional Directors. The foundation operates as a 501(c)(3) private foundation, a structure that allows the family to direct philanthropic capital while maintaining control over grantmaking priorities. Grantmaking spans three distinct program areas. Higher education scholarships form one pillar, directed toward individual students through processes not publicly detailed. Scientific and medical research grants constitute the second, alongside program sponsorships for classical music and opera organizations. A significant operational relationship exists with Jewish Family & Children's Service (JFCS), which receives recurring foundation support for healthcare center operations. The foundation also funds hunger relief initiatives, including food bank programs, though specific grant sizes and recipient organizations beyond JFCS remain undisclosed in public filings. The Winston family's philanthropic vehicle is intertwined with Winston & Winston, a law firm with offices in Scarsdale, New York and Scottsdale, Arizona, where Allan and Diana Winston practice. This dual structure — a law firm generating professional income alongside a foundation distributing charitable capital — mirrors a common pattern among small family foundations where the principals fund philanthropy through operating business cash flows rather than managing a dedicated endowment pool. No AUM figure or total annual grantmaking budget appears in available public records. What distinguishes this foundation structurally is its simplicity. No separate philanthropic structure or donor-advised fund affiliation has been disclosed.
