The Jefferson County Development Corporation is part of a larger network promoting our local economy. Although the organizations of the Jefferson County Chamber of Commerce, the City of Mount Vernon Tourism Department, and the Downtown Mount Vernon Development Corporation are separate entities, all four groups believe and practice collaboration and support of each other and their programs.

The Jefferson County Chamber of Commerce

has over 440 members, including home-based businesses, non-profit organizations, and large corporations. Their job is to serve members through promotion, networking opportunities, and assisting businesses and organizations to thrive and reach their goals.
