As Detroit continues a concerted effort to remake its image and turn its fortunes, the arts and culture have been playing a big role.

A marketing specialist, Dumas says that her goal will be to find ways to connect the area’s larger arts organizations, such as the Detroit Symphony Orchestra, with smaller, more flexible groups, in an effort to craft a cohesive arts strategy for a city on the mend.
