Dean Olsen had a successful stint in advertising and marketing in New York City, Chicago and London. But his high-flying career came crashing down after an addiction to alcohol contributed to a downward spiral that landed him in a Madison homeless shelter. Now, he has turned his life around and returned to UW-Madison Geography Department to earn a capstone certificate in GIS. And he’s starting a new business, LifeMapping, in which he uses his geography skills and advertising experience to help people preserve their life stories.
