Gerry Foundation

The Gerry Foundation launched in 1997, the year after Alan Gerry closed the $2.7 billion sale of Cablevision Industries to Time Warner (per the New York Times, 1996). The sale capped a career that began in 1956 when Gerry strung a single antenna on a hilltop in Liberty, NY to pull in New York City television signals for rural Sullivan County. The foundation was structured as an operating foundation, meaning it runs its own programs rather than solely distributing grants — a structural choice that allows it to act more like a developer and venue operator than a traditional philanthropy. Gerry deployed foundation capital into brick-and-mortar economic development in upstate New York, with the Bethel Woods Center for the Arts as the anchor asset. The 15,000-capacity amphitheater, museum, and 800-acre campus sits on the original Woodstock festival site and generates earned revenue through concerts, festivals, and tourism. Complementary holdings include the CVI Building in Ferndale, a commercial property tied to the foundation's broader Sullivan County revitalization footprint. In healthcare, the family funded the Paul Gerry Dialysis Center in Sayre, Pennsylvania, named for Alan Gerry's late son. Total assets under management are not publicly disclosed by the foundation; Altss estimates the portfolio at $100 million to $120 million based on 990-PF filings and real estate holdings. Alan Gerry's son, Adam Gerry, chairs Granite Associates — a separate venture and private equity firm — while his wife, Sandra Gerry, founded Sullivan Renaissance, a community beautification and civic engagement program that merged into Sullivan 180. Adam Gerry and his wife Ashley are also trustees of the Naples Children & Education Foundation, reflecting a secondary philanthropic hub in Florida. The foundation functions as a hybrid: part arts institution, part real estate developer, part community development lender. Its operating-foundation structure means program staff run venues directly rather than outsourcing to grantees, a model closer to the Barnes Foundation or Crystal Bridges than to a check-writing endowment. The concentration in a single economically distressed county makes it a high-conviction, geographically concentrated bet — the kind of focused allocation more common in family-run private foundations than in diversified institutional endowments.

Frequently asked questions

Where does the Gerry Foundation's capital come from?

The foundation was capitalized with proceeds from Alan Gerry's 1996 sale of Cablevision Industries to Time Warner for $2.7 billion. Gerry built Cablevision Industries from a single antenna on a Sullivan County hilltop into the country's eighth-largest cable operator before the exit.

Is the Gerry Foundation a grantmaker or an operating foundation?

It is structured as an operating foundation, which means it directly runs programs and venues rather than exclusively distributing grants. The Bethel Woods Center for the Arts — the foundation's signature asset — employs its own staff and earns venue revenue through concerts and tourism at the historic Woodstock site.

What is the relationship between the Gerry Foundation and Granite Associates?

Granite Associates is a separate venture capital and private equity firm chaired by Adam Gerry, Alan Gerry's son. The two entities are distinct: the foundation focuses on non-profit economic development in Sullivan County, while Granite Associates operates as a for-profit investment firm with a broader mandate.

Does the Gerry Foundation have any connection to Florida philanthropy?

Yes, indirectly through family members. Adam Gerry and his wife Ashley are trustees of the Naples Children & Education Foundation, a major Florida philanthropic organization known for the Naples Winter Wine Festival. The family also maintains residential real estate in Naples, Florida.

What role does Sandra Gerry play in the foundation's work?

Sandra Gerry, Alan Gerry's wife, founded Sullivan Renaissance — now Sullivan 180 — a community development and beautification program that operates alongside the foundation's economic redevelopment work. It is a distinct initiative focused on civic engagement, youth leadership, and small-scale community grants in Sullivan County.
