Joe McMahon, Founder

Joseph McMahon, P.E., and Chief Executive Officer, started his solo practice from home in Pennsylvania in 1976. Now more than 120 talented McMahon engineers and support staff in thirteen offices along the East Coast represent Joe’s passion for excellence in transportation engineering and people-oriented service.

Having expanded to a full-service transportation engineering firm, our work includes expertise in bridge design, hydraulic analysis, and GIS-GPS mobile data collection and review.

Recognized through the years as a top employer dedicated to continuous training for each staff member, McMahon Associates has, in turn, achieved consistent engineering excellence.
