White Plains Hospital Medical Center and Subsidiaries

White Plains Hospital Medical Center and Subsidiaries

White Plains Hospital was founded in 1893 and now operates as the Montefiore Health System's tertiary hub in the Hudson Valley. President and CEO Susan Fox leads the 292-bed not-for-profit, which delivers acute and preventive care across Westchester County and surrounding areas. The hospital sits at the center of a broader ecosystem that includes the White Plains Hospital Center Foundation, its primary philanthropic vehicle, and a direct real estate portfolio spanning commercial medical buildings and raw land in New York State. The hospital's investment portfolio is funded by operating surpluses from its clinical service lines and by foundation gifts. Real estate holdings include the main campus at 41 East Post Road; the Center for Advanced Medicine & Surgery at 122 Maple Avenue; a development site at 77 W. Post Road; medical offices at 99 Business Park Drive in Armonk; and a commercial facility at 1296 North Avenue in New Rochelle. The hospital board oversees deployment, with Apollo Global Management co-head Scott Kleinman serving as a board member alongside Chairman William Null. The portfolio mandate blends traditional endowment-style allocations with direct commercial real estate tied to the hospital's own expansion. Board governance connects the hospital's financial management to institutional private equity expertise through Kleinman's seat. On the philanthropic side, the White Plains Hospital Center Foundation Board includes honorary member Mariano Rivera. The hospital holds professional network memberships in the Westchester County Association — where Fox chairs the executive board — the Greater New York Hospital Association, and the Healthcare Association of New York State. The hospital has recently been executing a tower expansion project at its main campus. White Plains Hospital is unusual among community hospitals for running a dedicated real estate subsidiary that holds development-ready land and commercial properties separate from the clinical enterprise. This structure allows the hospital to align its investment portfolio with its own real estate growth needs — a supply-chain-like posture more common among university endowments than among regional medical centers.
