What GZA GeoEnvironmental, Inc. does
GZA GeoEnvironmental, Inc. is a multi-disciplinary engineering and environmental consulting firm founded in 1964 in Norwood, Massachusetts by Don Goldberg and Bill Zoino. The company is structured as a private, employee-owned firm with 800+ professionals distributed across more than 31 offices throughout the United States, and has reported gross revenues exceeding $100 million annually as of 2019. Its service portfolio spans approximately 20 practice areas, with the heaviest emphasis on geotechnical engineering, GeoStructural/construction engineering, environmental site investigation and remediation (including PFAS and emerging contaminants), EHS regulatory compliance, dams/levees/hydropower, waterfront and coastal engineering, natural resources and ecological services, construction management, and data management/analytics/visualization including 3D modeling and VR/AR solutions for infrastructure.
Revenue is generated through project-based professional engineering consulting engagements executed across multiple verticals: transportation and infrastructure (bridges, highways, airports, tunnels), buildings and real estate development, industrial, water, government (federal, state, local agencies and authorities), institutional, and select legal and agricultural accounts. Commercial model is direct-client engagement through business development and established client relationships, with no disclosed pricing; the firm markets through its corporate website, an annual Walter E. Jaworski Technical Conference, social media, and trade publication thought leadership. Named clients span public-sector (City of Northampton, NASA, Port Authority of New York and New Jersey) and private-sector (Novartis, National Development, Firmenich, Block Island Offshore Wind Farm), with marquee engagements including the Gordie Howe International Bridge and NASA Mobile Launcher 2 (the latter absorbed via the 2025 Siefert Associates asset purchase). The firm has completed over 100,000 projects since founding, including 50,000+ environmental site investigations since the 1970s and 60+ Superfund projects across 8 EPA regions.
