## About

Overbrook Management Corporation was formed in 1946 by financier Frank Altschul to steward the Altschul family's wealth. Leadership passed to his son Arthur Goodhart Altschul and then to grandson Arthur G. Altschul, Jr., who serves as Chairman and CEO. The firm remained a single-family office until 2002, when it began accepting outside clients while staying privately owned and serving four generations of the founding family. The firm allocates across public equities, private equity, hedge funds, real estate and commodities. Portfolios combine single-name securities selected for sustainable returns on capital with allocations to alternative managers. Overbrook participates in direct co-investments and fund-of-funds structures. All investments occur in North America. The firm states it invests its own capital alongside clients in the same strategies. Overbrook employs a research and operations team that includes President Richard Zenker, CIO Ryan Kanaley and COO Frank Siciliano. The firm maintains its sole office at 280 Park Avenue in New York. In late 2025 it hired Peter Kunze, formerly of J.P. Morgan, as Executive Director. Philanthropic ties include The Overbrook Foundation and the Child Mind Institute, where Arthur G. Altschul, Jr. serves on the board. Overbrook's structure preserves the original single-family mandate while operating as an SEC-registered advisor open to additional families. This hybrid allows continuity of the Altschul investment philosophy across both proprietary and external capital without shifting to a product-driven model.
