Triumvirate Environmental
Hiring · 141 open jobsGeneral information
Triumvirate Environmental provides environmental services and EHS consulting to companies in life sciences, manufacturing, healthcare and education. The company is based in Somerville, Massachusetts, in the United States.
It started in 1988 in Boston as a three-person operation, founded by John McQuillan. In February 2025, Berkshire Partners bought a majority stake, valuing the company at $1.8 billion. Triumvirate had earlier grown through deals, including two acquisitions completed in 2014. That matters: private-equity backing gives Triumvirate money to expand its environmental and waste-management services and to keep buying smaller companies. Triumvirate Environmental is an H-1B sponsor.1
