MARCH 09, 2017 – GERTRUDE, INC.™, the Chicago-based boutique ad agency, has been handed something close to a mission impossible. But one that will be fun to carry out, no matter how challenging. GERTRUDE has been tasked with developing the advertising strategy for the rollout of the SafeHouse Chicago, a spinoff of a 50-year-old Milwaukee institution that Marcus Hotel & Resorts has, in rather covert fashion, brought to the Chicago market.
