Joseph McMahon founded McMahon Associates, Inc., in 1976 after a decade of transportation consulting throughout the United States and Canada. Joe’s vision and drive built our successful firm from a single practitioner to more than 200 employees in 15 offices. While Joe has stepped away from day-to-day operations of the firm, he continues to serve as adviser to the Board and executive leadership of the firm, serves on several committees and participates in the firm's mentoring program. 

Joe continues to actively mentor aspiring engineering students through his alma mater, Villanova University, and he and his wife, Peggy, manage the Joseph and Peggy McMahon Transportation Scholarship Fund. They also continue their longtime passion of traveling the world gathering information on transportation systems and sharing this knowledge in lectures with McMahon staff and at various universities.
