The Jaharis Family Foundation concentrates its philanthropic support on higher education—especially medical education—and a small set of cultural and faith-based institutions. Grants are sizable and directed to a handful of repeat recipients, reflecting long-term relationships with major medical schools (Columbia and Tufts), a Greek Orthodox seminary, and a prominent New York cultural institution. The foundation’s giving mixes strategic institutional support for professional training with stewardship of cultural and religious heritage.
A defining feature of The Jaharis Family Foundation C/o Oikos Holdings LLC is its repeated, large-scale support for medical education. In the recent grants list, Columbia University Medical College appears with multiple seven-figure awards in 2025 and 2024, while Tufts University School of Medicine also received several major grants across both years. That pattern points to sustained institutional backing rather than one-time project funding. The foundation’s giving also reaches beyond medicine into a smaller set of cultural and faith-based institutions. Hellenic College Holy Cross received several substantial grants, and The Metropolitan Museum of Art appears with more than one award. Other recipients in the recent record include Haverford College, Northwestern University, PBS - WNET, West Side Campaign Against Hunger, Trinity School, and the National Hellenic Museum. Across the grant list, the foundation’s support is concentrated among a limited number of recipients, with multiple awards going to the same institutions in different years. The mix of higher education, cultural organizations, and community-serving nonprofits suggests a portfolio built around long-running institutional relationships.
Medical education stands out as the clearest cause area in the recent grants. The foundation gave $1,700,000 to Columbia University Medical College in 2025, and it also supported Tufts University School of Medicine with awards of $1,110,000, $1,100,000, and $1,100,000 across 2024 and 2025. Faith-based and Hellenic institutions are another consistent theme. Hellenic College Holy Cross received $392,101, $389,227, and $371,760 in recent grants, indicating repeated support for theological education. The portfolio also includes arts and public-service organizations. In 2025, the foundation gave $750,000 to the Art Institute of Chicago and $500,000 to The Metropolitan Museum of Art. Community-serving grants also appear, including $50,000 each to West Side Campaign Against Hunger and PBS - WNET in 2025.
The stated typical grant size is $4,500 at the 25th percentile, $10,000 at the median, and $50,000 at the 75th percentile, while the recent record also includes several much larger institutional grants. The grant list shows repeat awards to the same organizations in both 2024 and 2025, especially in medical education and Hellenic education, which points to ongoing relationships rather than isolated gifts. The foundation’s structure includes family-fund management through Oikos Holdings LLC, and it funds individuals as well as organizations. The recent record shows grants in a wide range of sizes, from five-figure support to seven-figure commitments.
