In 1907 the Chamber of Commerce was officially chartered, the same year the first passenger cars operated on the interurban and the Brown Mansion was completed. For 100 years, the Chamber in Coffeyville has been committed to conducting activities which have a positive impact on the economic, educational, civic and social welfare of Coffeyville and the area.
