Jack, Joseph and Morton Mandel Foundation

The Jack, Joseph and Morton Mandel Foundation traces to 1953 when brothers Jack, Joseph and Morton Mandel created the entity. Its wealth originated in industrial and electronic component supply. The foundation maintains headquarters in Cleveland and an Israel headquarters in Jerusalem. The foundation allocates across private equity, public equities and real assets. Confirmed positions include holdings in The Riverside Company through Parkwood LLC and limited partnership interests in Deerfield Management, Lone Star Funds and Warburg Pincus. Geographic exposure centers on the United States and Israel. It integrates mission-related investing and program-related investing to align endowment assets with philanthropic objectives. Assets total an estimated $2 billion. The foundation maintains additional offices in Israel and supports vehicles including the Mandel Institute for Nonprofit Leadership. A recent operational event includes sponsorship of the Mandel Opera & Humanities Festival in Cleveland in May 2023. Parkwood LLC serves as the dedicated investment advisor and operating company, creating a hybrid structure that separates grantmaking from asset management while retaining family oversight through trustees.
