The Minneapolis-based Children’s Theatre Company, which won the Tony Award for best regional company in 2003, has completed a $27 million capital campaign four months ahead of schedule, and announced a special “encore” campaign aimed at raising another $3 million by year’s end. The fundraising has been largely targeted to cover construction costs on CTC’s new expanded home, designed by architect Michael Graves. The extra fund drive will seek to bolster the company’s endowment.
