Laborers International Union of North America

Laborers International Union of North America

The Laborers International Union of North America was founded in 1903. Brent Booker succeeded Terry O'Sullivan as General President on May 1, 2023. Michael F. Sabitoni serves as General Secretary-Treasurer and Joseph Mancinelli as International Vice President and Canadian Director. The union maintains pension assets as an asset owner. Confirmed holdings include residential properties such as 75 James and The William Thomas in Hamilton, Ontario, plus the Moreschi Building in Washington, DC. Additional assets encompass the New England Laborers' Training Trust Fund Headquarters in Hopkinton, Massachusetts, and the Hopkinton Training Campus Portfolio. Geographic reach covers the United States and Canada. Capital deployment occurs through direct ownership of union facilities and training infrastructure rather than external fund commitments. No public professional headcount or AUM figure is available. The organization maintains affiliations with the AFL-CIO through North America's Building Trades Unions and the Canadian Labour Congress. It operates the Terence J. O'Sullivan LIUNA Charitable Foundation as a separate philanthropic vehicle. The May 2023 leadership transition from O'Sullivan to Booker constitutes the most recent documented operational change. The union's structure ties investment decisions directly to member-benefit mandates and collective-bargaining outcomes. Real-estate and training assets function as extensions of labor-support operations rather than standalone portfolio strategies.
