Verdantas, an RTC Partners-backed provider of engineering, planning and science services to support their clients’ sustainability infrastructure objectives, has acquired Leighton Group.

Leighton Group offers geotechnical and environmental consulting and materials testing and inspection services. This addition to Verdantas looks to strengthen its western U.S. presence and brings depth to its geologic, geotechnical and materials capabilities.

“Leighton joining Verdantas marks a strategic inflection point in our ability to expand our service offerings to clients and extend our geographic reach,” states Gerry Salontai, CEO of Verdantas. “This commitment to excellent work for clients and Leighton’s efforts to capitalize on a collaborative environment fits well into Verdantas’ intentional people-focused approach.”

Greenberg Traurig LLP and Stradling, Yocca, Carlson and Rauth PC acted as legal counsel, and BDO USA LLP and CohnReznick LLP acted as financial and tax advisors on behalf of RTC and its affiliates.
