McMahon Associates

“Every 5 years McMahon seems like a different company because we keep growing; adding different services and new locations.”
— Joe DeSantis
President, McMahon Associates
2016 is a year of celebration for McMahon Associates. When the company was founded 40 years ago in the Dresher, PA home of Joe McMahon and his wife, they couldn’t have imagined the growth and expansion that the traffic and transportation engineering company would see decades later. Started as a traffic engineering company primarily for local developers, they have expanded their services to include traffic and roadway design, highway and street design, ITS (intelligent transportation services) bikeways, transit improvements, survey services, and bridges.

Most recently, McMahon Associates launched “Traisr”- an asset management system for local governments. This database utilizes geographic information systems technology to help its customers catalog and better manage their facilities, fleet management and vehicle tracking, snowplow tracking, and assists with permits, inspections and work orders.

President Joe DeSantis has been with the company for 30 years, working his way up from a staff engineer. Through Joe’s eyes, “every 5 years McMahon seems like a different company because we keep growing; adding different services and new locations.” Starting with only 9 employees, McMahon Associates now employs 170 full-time associates with 13 offices in Pennsylvania, New Jersey, Florida, Massachusetts, and Rhode Island.
