YEARS IN THE FIELD

BUILDING BETTER. EMPLOYEE-OWNED.

Ray Eriks founded Cambridge in 1988 with a clear focus in mind: building better building through tailored solutions. When Jeff Eriks took over, that focus didn't change. Built on years of experience, Cambridge has completed 275+ project across the nation. In June 2025, Cambridge became 100% employee-owned. For the team, it meant becoming true stakeholders. For our clients, it means working with people who treat every project like it's their own.

MEET THE TEAM DRIVING THE WORK.
