The mission of the Jefferson County Growth Association (JCGA) is to provide coordination of professional leadership to promote and support new and existing growth throughout Jefferson County, Missouri.


The Jefferson County Growth & Development Association was formed in 1988 to promote Jefferson County to home buyers, builders and developers. The organization evolved and grew to include the promotion of all businesses in Jefferson County. The organization was reorganized in January 2012 as the Jefferson County Growth Association (JCGA).

The Jefferson County Growth Association through Leadership, Membership, and Collaboration is making a positive difference where we live and work.
