Tom Hoch ran the nonprofit Hennepin Theatre Trust for more than 20 years, then stepped down earlier this year to run for Minneapolis mayor. In April, the trust tapped Mark Nerenhausen as its new president and CEO. The trust is an important anchor in downtown Minneapolis as operator of the State, Orpheum and Pantages theaters. Nerenhausen lands in his new role with new competition from venues like the Palace Theatre in downtown St. Paul. He also brings extensive arts administration experience and a fresh eye. The challenge will be finding a strategy to grow the trust’s programming, revenue and mission.
