Management / Office Staff

Kenn Wolf


773-588-0800 Ex. 120



Kenn started out interning summers during high school in the mid-70s. (Yes, Kenn and Loren were high school sweethearts.) Kenn credits Rodger, his father-in-law, for letting him try out new ways of running the business, and how he graciously allowed him to take charge over time. Kenn really liked business school at DePaul, applying some of what he learned early on by introducing computerization to Frerk's bookkeeping and inventory systems. This not only increased efficiency, but allowed them to serve customers better. His favorite hobby? Kenn wishes he had more time for sailing his boat on Lake Michigan.
