Meet TMACC

TMACC was founded in May of 1992 as the Chester Valley TMA and consisted of 14 Founding Members, which include some of our current members today: Chester County Intermediate Unit, Great Valley Regional Chamber of Commerce, Krapf’s Coaches, Inc., PennState Great Valley, and Saul, Ewing, Remick & Saul.  In June of 1995, the Chester Valley TMA Board of Directors changed our name to the Transportation Management Association of Chester County to better capture the members we wanted to acquire.

The mission of TMACC is to advance equitable, safe, and sustainable multimodal transportation solutions by serving as

  • a resource center for innovative mobility strategies,
  • a collaborator of the public, private, and non-profit sectors, and
  • a catalytic agent for advancing and implementing best practices.

Today, TMACC represents the expanding region of Chester County and continues to advocate for sustainable transportation practices and connectivity. TMACC’s membership represents over 20,000 commuters in Greater Philadelphia and includes a range of organizations in engineering, planning, law, consumer goods, finance, hospitality, education and more.
