Hirtle, Callaghan & Co.
Jonathan J. Hirtle and Donald E. Callaghan established the firm in 1988. Both arrived from Goldman Sachs vice-president roles. The firm positions itself as an outsourced CIO rather than a product manufacturer. Allocations span public equities, hedge funds, private equity, private credit, real estate, and natural resources. The firm executes through direct co-investments, fund commitments, and secondaries. Confirmed holdings include positions tied to The Barnes Foundation and The Wortham Foundation. Geographic reach covers North America, Europe, Asia, and Africa. The firm employs professionals across six offices in addition to headquarters. Brad Conger serves as chief investment officer. Robert J. Zion serves as chief operating officer. In 2014 the firm joined the Intentional Endowments Network to advance ESG integration. HC Capital Trust operates as an adjacent vehicle. The firm maintains an open-architecture model that avoids proprietary funds. This separates advice from product distribution. Governance includes independent trustees such as R.W. Wortham III.
