Langan Engineering & Environmental Services, a 500-employee, privately held consulting firm, headquartered in Elmwood Park, NJ, has established a West Coast beachhead with the acquisition of  Treadwell & Rollo, a 70-employee geotechnical and environmental engineering firm based in San Francisco. 

It’s the first acquisition in Langan’s history and gives the firm a new market for its services in San Francisco, Oakland, San Jose, and Sacramento where Treadwell & Rollo has offices.

In a news release, Langan said:

“In an era where large public corporations have routinely acquired smaller firms, the Langan/Treadwell & Rollo deal signifies a strategy for growth and expansion between two independent firms. As a result, the combined forces of Langan and Treadwell & Rollo will instantly attain true nationwide reach; have access to shared technical resources; and remain privately held, which enables swift responsiveness to client needs on all projects.”

Langan’s major projects include the New Meadowlands Stadium for the Giants and Jets, the Four Seasons Hotel (the tallest building in South Florida), and the Shops at Atlas Park, which won the 2007 Phoenix Award, EPA Region 2.

The firm also supports development projects for academic institutions, hospitals, and governmental agencies, as well as large-scale national and international infrastructure projects. Langan’s environmental practice specializes in compliance programs for major corporations in the petro-chemical, utilities, and manufacturing industries, and is active in remedial designs for brownfield and Superfund sites.

In New Jersey, Nick DeRose, a Langan Senior Principal, serves as president of the  Licensed Site Remediation Professional’s Association.  His colleague, Dr. Jorge Berkowitz, was appointed by Governor Chris Christie to serve as a member of the state’s Licensed Site Remediation Professional’s Licensing Board.
