## About

Lighthouse Guild International traces its roots to 1906, founded as a charitable organization to serve the blind and visually impaired. Chairman James M. Dubin, a former senior partner at Paul, Weiss, Rifkind, Wharton & Garrison LLP, leads a board that includes Vornado Realty Trust Vice Chairman David R. Greenbaum and Kahn Brothers Group President Thomas G. Kahn. The foundation operates from its headquarters at 250 West 64th Street in Manhattan. The organization funds its operations through a dedicated investment portfolio and beneficial interests in perpetual trusts. While exact AUM is undisclosed, the portfolio supports a multi-site healthcare delivery system with clinics in Albany, Buffalo, and Niagara Falls. The asset base leans on direct endowment holdings and real estate assets, including its headquarters and regional clinical properties, rather than a fund-of-funds approach. The investment posture supports vision rehabilitation, technology development, and advocacy programming rather than external co-investment structures. Board member David R. Greenbaum connects the foundation to the Real Estate Board of New York, while the Palm Beach Friends of Lighthouse Guild extend its philanthropic network into Florida. The foundation has not announced any new pooled funds or fundraising vehicles in the past 24 months. The endowment's structural distinction lies in its perpetual trusts — an arrangement that provides long-term financial ballast outside the typical spend-down pressures of self-liquidating charitable foundations. This trust structure, combined with direct real estate holdings, creates a balance sheet that functions more like a legacy institutional endowment than a program-dependent nonprofit, though the organization does not publicly report investment performance or total corpus size.

## Questions

### Who oversees investment decisions at Lighthouse Guild?

Lighthouse Guild does not publicly disclose a chief investment officer or external OCIO. Governance sits with the board, which includes David R. Greenbaum of Vornado Realty Trust and Thomas G. Kahn of Kahn Brothers Group. Day-to-day financial management is supported by Assistant Treasurer Marios Damianides, a partner at Ernst & Young. The organization has not published an investment committee charter or meeting minutes.

### What is the source of Lighthouse Guild's endowment funding?

The foundation does not disclose the original donors or wealth origin of its perpetual trusts. Its funding base reflects over a century of charitable giving rather than a single-family fortune. Real estate holdings provide an additional asset class that generates operational income and long-term appreciation.

### How does Lighthouse Guild separate its investment activities from its charitable mission?

The foundation operates its healthcare, rehabilitation, and advocacy programs directly from its New York facilities, funded by the investment portfolio. No program-related investment (PRI) or mission-related investment (MRI) framework has been publicly described. The investment corpus functions as a traditional endowment financing the charitable operating budget.
