## About

The Open Door Foundation was established in 1990 as a 501(c)(3) nonprofit, operating as the fundraising and development arm of the Open Door Family Medical Center. Farrell has guided the organization from its inception, building a structure where the foundation’s endowment and donor capital directly support clinical operations and community health initiatives across Westchester, Dutchess, Putnam, and Ulster Counties. The foundation’s capital deployment is concentrated entirely on sustaining and expanding the services of the Open Door Care Network. This includes underwriting primary and specialty medical care, dental services, behavioral health programs, and the Women, Infants, and Children (WIC) nutrition program. Unlike foundations with broad grantmaking portfolios, the Open Door Foundation functions as a single-asset vehicle: its investment portfolio exists to generate returns that subsidize a specific care network delivering culturally competent, multilingual services to a predominantly low-income patient base. Governance includes board members with professional backgrounds beyond the nonprofit sphere, such as Patrick Whalen, CEO of the crypto asset manager Liquid Digital, and Noi Sukaviraya, a user experience researcher at IBM. The foundation maintains a physical footprint tied to its clinical network, with a headquarters at 165 Main Street in Ossining and an affiliated facility at 300 North Broadway in Sleepy Hollow. Farrell’s dual role as President and CEO of both the foundation and the medical center ensures tight alignment between fundraising strategy and on-the-ground care delivery priorities. The foundation’s structural differentiator lies in its total operational integration with the medical provider it funds. The chief executive and core administration are shared entities, meaning investment returns and donor dollars flow directly into operating budgets for a single clinical network rather than being reviewed by an external grants committee. This architecture eliminates the typical foundation-program gap; the asset pool is managed explicitly to stabilize and grow a community health system that provided care to its patient base regardless of insurance status or ability to pay.
