What J.T. Magen & Company Inc. does
J.T. Magen & Company Inc. is a privately held construction management firm founded in 1992 by Maurice Regan and headquartered in New York City. The company delivers full-service construction management for complex commercial interior projects, organized around three phases: pre-construction planning, on-site construction execution, and close-out services. Operations extend across six offices in New York, Los Angeles, Chicago, Miami, Austin, and Toronto, with licensing in 40 states, U.S. territories, and Canadian provinces. The firm employs 251–500 people and ranks among the Top 50 U.S. General Contractors, including ENR #7 New York (2023) and BD+C Giant 400 #36 (2025).
The firm serves enterprise clients across law firms, financial services, TAMI (technology, advertising, media, information), retail and luxury brands, data centers, healthcare, and hospitality. Named clients include Skadden Arps, Meta, TikTok, Nike, Cartier, Equinix, Macquarie Group, Mount Sinai Health System, Wayfair, and Hudson River Trading. J.T. Magen differentiates through in-house MEP, BIM, LEED/WELL certification, and safety expertise, plus early engagement in design phases to reduce change orders. The company also operates national rollout capabilities for multi-location programs spanning H&M, Foot Locker, Tiffany & Co., Primark, Microsoft, and Adidas.
Revenue is generated through project-based construction management contracts for commercial interiors, with pricing determined by project-specific estimation. The go-to-market is a relationship-based enterprise sales motion targeting Fortune 500 companies, major property developers, landlords, and brands. J.T. Magen has no public revenue disclosure, no parent company, and no disclosed institutional investors. In March 2026, the firm partnered with Extell Development and HYM Investment Group to win a $75 million foreclosed development site in South Boston, marking a first identified step into developer/owner economics beyond pure construction management.
