After four years of deficits, the Children's Theater Company is finally operating in the black. The Company announced this week that it has an operating surplus of $175-thousand dollars on a $7.1 million dollar budget. In the past year, attendance increased 24-percent. Director Peter Brosious credits enthusiastic Twin Cities arts patrons for the turnaround. He says the audience responded to the theater's recent attempt to offer a broader selection of plays.
