TPD Advances on ENR’s List of Top 500 Design Firms in the Nation

In our 4th year on the list, TPD has hurdled over the 400’s, landing at #395 on Engineering News Record (ENR)’s Top 500 list of Design Firms in the Nation. ENR is recognized as the leading engineering and construction news publication in the United States; their Top 500 list ranks the largest domestically based designs firms, both publicly and privately held, based on revenue. TPD made our inaugural appearance on the nationally acclaimed list in 2021, joining at number 450.

With over 300 members, 16 office locations, and an ever-expanding repertoire of services, TPD has achieved notable growth over the past few years. Kevin Johnson, TPD’s President, attributes the firm’s success to “our dedication to investing in a talented and diverse staff of professionals, in addition to our exploration of new service-driven and geographic opportunities, while operating as lean and strategically as possible.”

TPD is a transportation engineering firm that serves the eastern United States with offices across Pennsylvania, New Jersey, Delaware and the Carolinas. Additionally, we are consistently ranked as one of the Best Civil Engineering Firms to Work for in the nation by the Zweig Group.
