Mark Hanson took over as president of the Milwaukee Symphony Orchestra in January 2004, and it didn’t take him long to decide that what the financially strapped organization needed was a completely new way of doing business. Whereas previous administrations tried to patch deficits by dipping into the endowment, and sought to downplay the importance of dramatically slumping ticket sales, Hanson is apparently seeking to face the MSO’s problems head on, and in public. Still, that means more deficit spending for the next couple of seasons, and an uphill battle to convince local donors that the symphony is worth their investment.
