What Martin Bros does

Martin Bros (legal entity Martin Brothers Marcowall Inc) is a Gardena, California-headquartered specialty trade contractor founded in 1932 by William Martin and operating exclusively across Southern California. The company self-performs the interior and exterior framing, drywall, fireproofing, plaster, acoustical, and Division 10 scopes on commercial construction projects, acting as a subcontractor to general contractors and serving owners across aviation, healthcare, hospitality, entertainment, retail, education, cultural, residential, and municipal end-markets. Notable project credentials include SoFi Stadium (3.1 million sq ft, completed September 2020 under a JV with Nevell Group), the LAX Tom Bradley West modernization, Walt Disney Concert Hall, the Academy Museum of Motion Pictures, multiple Kaiser Permanente facilities, and the Louis Vuitton Rodeo Drive flagship.

The company layers advanced construction technology on top of its trade work: an in-house BIM and VDC department (launched June 2000), a prefabrication facility producing drywall shapes, soffits, column covers, and medical head walls, and AR/VR field tools built around Microsoft HoloLens for layout visualization and 4D virtual tours. Proprietary historical innovations include the shaft wall system co-developed with Tishman and USG in 1965, direct-to-steel fireproofing (1955), and what the company describes as the construction industry's first internal ERP for payroll (1975). Operations are supported by offices in Gardena, Jurupa Valley, and San Diego, with a workforce in the 501–1000 range and an Experience Modification Rate of 0.65 in 2025, well below the industry average of 1.0.

Martin Bros generates revenue through project-based construction contracts — fixed-price or cost-plus — awarded via competitive bidding and negotiated agreements with general contractors, with joint-venture arrangements used on the largest scopes. The company has been 100% employee-owned since July 2018, with no external parent, private equity, or institutional investor. Cumulative contract value across its history exceeds $4 billion and its portfolio spans over 100 million square feet of completed California commercial space, though annual revenue is not publicly disclosed.
