OUR MISSION: The O’Fallon Chamber of Commerce is committed to promoting economic vitality in O’Fallon and the St. Charles County Region while providing members with networking opportunities, education and advocacy in public policy decisions affecting business.

For more than 50 years the O'Fallon Chamber has been the organization the community has counted on as its source for local information, relocation assistance, and business referrals.

Since the mid-1990's, the City of O'Fallon has experienced phenomenal growth.  O'Fallon has grown from 18,700 in 1990 to approximately 66,000 in 2004 while attracting its two largest employers, MasterCard International and CitiGroup.

As businesses continue to open and our community continues to grow, so does the Chamber.  Now numbering more than 550 businesses, the Chamber is the organization businesses turn to for community information, and valuable networking opportunities and referrals, to increase their business.  From monthly membership luncheons, to networking groups, to member mixers, and other special events, the Chamber is a valuable business resource.
