About Us

Chicago General Contractor (CGC) is the brainchild of Donny Zanger, a serial entrepreneur originally from Philadelphia, and Juan Ruden, a veteran contractor with 15 years of experience in the general contracting space in the Chicago metropolitan area. Donny and Juan Ruden met at a building convention in Chicago when Donny was splitting his time between Chicago and New York City, and they instantly developed an easy-going chemistry that they knew would turn into something special. The idea behind CGC was simple – become a one-stop-referral-shop where Chicagoans, both business owners and homeowners alike, can turn their vision of their dream renovation projects into a reality. Before teaming up with Juan to found GC, Donny spent fifteen years in general contracting, starting shortly after finishing college. In addition to his thriving contracting business, Donny is also the founder of several technology companies, including some that made a successful exit while others are still up and running independently. The independent general contractors in CGC’s referral network of builders have worked with some of the biggest players in Chicago and the Midwest, including Goldfinch, the Rhona Hoffman Gallery, Chicago Truborn, and many others. CGC’s team is proud to have its referral network serve every type of client, big or small. The independent general contractors in CGC’s referral network guarantee uncompromising attention to detail and satisfaction with every project.
