Both Bob & Diane Greenlee are Iowa State grads. After leaving Iowa State, Bob helped form Fultz, LaCasse & Greenlee, a full service advertising agency and public relations firm in Des Moines. In 1975 Bob and Diane purchased KADE an AM radio station in Boulder, Colorado. Two years later they bought a nearly bankrupt FM station there and built it into one of the top rated stations in the Denver, Colorado market. They sold their interest in both stations in 1990. The Greenlee’s and a Colorado restaurateur began operating the Walnut Brewery brewpub in Boulder in 1991 that became the Rock Bottom, ChopHouse, and Old Chicago restaurant group. The group was recently merged with Gordon Biersch and now operates over 150 restaurants nationwide.
