History of ABM
- Founded: 1909
- Founders: Morris Rosenberg
The brand began in 1909 when Morris Rosenberg started a window washing business in San Francisco named American Building Maintenance. It grew with the office building boom into a national janitorial contractor and listed on the NYSE in 1962.
Through decades of acquisition the name covered parking, aviation, engineering, and technical services as each business was added. The corporate identity shortened to ABM as the portfolio outgrew its janitorial origins.
Under CEO Scott Salmirs since 2015, the brand has been repositioned around integrated facility solutions and technical work, including the 2025 move into semiconductor fab services through the WGNSTAR acquisition.
