Eparchy of Saint Maron of Brooklyn

The Eparchy of Saint Maron of Brooklyn was established in 1966 as the first Maronite diocese outside Lebanon, with jurisdiction over Maronite Catholic faithful along the U.S. East Coast. Headquartered at 109 Remsen Street in Brooklyn, New York, the eparchy operates under Bishop Gregory Mansour and remains immediately subject to the Holy See, while maintaining ecclesiastical ties to the Maronite Patriarchate of Antioch. Unlike a conventional charitable foundation, the eparchy holds a substantial portfolio of operating religious properties — including Our Lady of Lebanon Maronite Cathedral, a seminary in Washington, D.C., and the Most Holy Trinity Monastery in Petersham, Massachusetts — which anchor its balance sheet and generate ongoing operational demands. The endowment deploys capital across distressed debt, mezzanine financing, secondaries, and special situations, with a posture that suggests an opportunistic, value-oriented mandate rather than a passive allocation model. Real estate holdings form a structural backbone, including the cathedral complex in Brooklyn Heights, the Saint Sharbel Spiritual Life Center in Pittsburgh, and the Heart of Jesus Maronite Catholic Church in Fort Lauderdale. The investment office appears to source deals through ecclesiastical networks and lay professional connections, with co-investment relationships documented with the Anthony R. Abraham Foundation, the Koch Foundation, and the Catholic Extension Society — all of whom have provided matching grants for parish endowments and eparchial infrastructure. The eparchy comprises 45 parishes and missions, supported by a professional and clerical staff of undisclosed size. Philanthropic activity is channeled through the Order of Saint Sharbel, which operates separately from the endowment's investment arm. Bishop Mansour participates in the United States Conference of Catholic Bishops, and the eparchy maintains close coordination with the National Apostolate of Maronites, its official lay partner. In October 2023, the eparchy publicly launched a capital campaign to fund renovations at the cathedral and expand seminary housing, signaling continued investment in its physical infrastructure. The eparchy's structural differentiator lies in its dual identity as both a religious operating enterprise and an opportunistic investor. Unlike most endowments of comparable size, it carries a portfolio of consecrated real assets that serve an active liturgical mission — a liquidity profile and fiduciary complexity that shapes how it must manage its financial reserves. No external OCIO arrangement has been disclosed, suggesting investment decisions remain internal or closely held.
