About Us

CEMCO was formed as an electrical manufacturer’s representative firm in 2003. The company was formed by combining the resources of MS2 and the Hanke Co. Inc., two firms with established roots in the Northern Illinois electrical industry.

In 2010, Mark Franzen purchased the shares of his two partners, becoming sole owner of the company.

Our combination of knowledge and general industry experience provide our manufacturers with a unique position in the Northern Illinois marketplace.


October 1, 2010 CEMCO relocated to 476 W. Wrightwood Avenue in Elmhurst, IL. In keeping with current industry trends, we have moved into an office space only to accommodate growth of our inside and outside sales groups. This facility allows us to transition from the rep distribution function of the 1970’s and 1980’s to the era of reps performing true sales and marketing functions.
