Partner Ranked on ENR's Top 200 Environmental Firms List for the 14th Consecutive Year

October 20, 2026 - 22:48

Partner Engineering and Science, Inc. has moved up 25 places on Engineering News-Record's 2026 Top 200 Environmental Firms list. This marks the 14th consecutive year the firm has earned a place on the ranking, which tracks the largest environmental services companies in the United States based on revenue from environmental work.

The jump in position reflects steady growth across the firm's environmental practice, including site assessment, remediation, compliance and due diligence services. Company leaders credited the climb to expanded client demand and a broader geographic reach, along with repeat work from long-term clients in the real estate, energy and industrial sectors.

The ENR list is compiled annually from revenue figures reported by participating firms, and placement is closely watched as a measure of market standing in the environmental consulting industry. Partner's 14-year streak puts it among a relatively small group of firms that have appeared on the ranking every year since first qualifying.

Firm representatives said the recognition points to consistent performance rather than a single strong year. They also noted plans to keep investing in technical staff and regional offices as environmental regulations and cleanup obligations continue to drive demand for consulting and engineering services nationwide.
