Walsh Brothers

What Walsh Brothers does

Walsh Brothers, Incorporated is a privately held, fourth-generation family-owned construction management firm headquartered at 210 Commercial Street, Boston, Massachusetts, founded in 1901 by brothers James and Thomas Walsh in Cambridge, Massachusetts. The firm specializes in full-service construction management for complex, sensitive building projects — including preconstruction planning, constructability analysis, BIM/VDC-driven coordination, 4D sequencing, Lean Construction methodology, sustainable construction (LEED-certified delivery), and risk management — and delivers these services primarily to healthcare systems and academic/research institutions in the New England region.

Walsh Brothers serves a concentrated set of institutional clients across eight verticals: healthcare and hospital, academic and research, laboratories and life sciences, arts and cultural institutions, athletics and stadiums, commercial, historic restoration, and residential. Anchor relationships include Mass General Brigham (multi-decade), Brigham and Women's Hospital, Dana-Farber Cancer Institute, Boston Children's Hospital, Mount Auburn Hospital, Harvard, MIT, Boston College, Boston University, and the Boston Red Sox. The firm has earned National AGC Safety Awards (Zero Incidence Rate in 2021, 2022, and 2024) and is recognized as one of the safest contracting firms in the U.S.

The business model is negotiated, project-based construction management fees for professional services spanning project conception through closeout. Go-to-market is direct, relationship-based enterprise sales in which principals engage owners, architects, and owner's project managers personally. The firm pursues mega-projects via joint ventures (e.g., Turner Construction on the 1.9M SF Ragon Building at MGH; Commodore Builders on the 350,000 gsf Veterans' Home at Holyoke), allowing the ~200-person organization to access scale beyond its standalone headcount. Revenue and financial data are not publicly disclosed.
