Tetra Tech Rizzo History
Tetra Tech Rizzo was founded as Rizzo Associates, Inc., in 1983 by Bill Rizzo, Jim Carlin, and John Bewick. A civil engineer with particular expertise planning engineering projects, Bill had served as the Assistant Secretary of Transportation for the state of Massachusetts under Governor Edward King. With the election of a new governor, Bill decided to establish Rizzo Associates as a full-service environmental consulting and engineering services firm. Jim Carlin, the former Massachusetts’ Secretary of Transportation/Chairman of the Massachusetts Bay Transportation Authority, was the firm’s financial partner. John Bewick, the former Massachusetts’ Secretary of Environmental Affairs, was also part of the team.
The firm started out in a small space in Framingham, Massachusetts. The young company grew quickly with expansion in the initial years partially driven by the passage of Massachusetts General Law, Chapter 21E, the state Superfund law, which required the assessment and cleanup of thousands of contaminated waste sites in the state. Rizzo Associates was involved in some of these early cleanup projects. Its initial focus was to provide “one-stop shopping” for private clients who typically wanted to build a commercial or retail facility. Services typically included hazardous waste/remediation, permitting, and civil/site engineering, and later transportation and water/wastewater engineering.
Moving to a larger space in Natick in 1984, the growing company soon added several key staff members including Rick Moore, as Director of Environmental Projects, Liz Levin as Marketing Director, and Rick Hughto as Director of Hazardous Waste Projects. In 1987, Rizzo acquired Bethel Duncan Associates to tap into the superb engineering expertise of Dave Duncan.
