“The departure of Colorado Ballet’s executive director two weeks ago has set off a chain reaction of resignations, including the company’s board chairwoman, its head of sales and marketing and five other board members. At the same time, the company still owes the city of Denver $146,629 in rent and other fees from its fall production of “Dracula” in the Buell Theatre. And it will owe about $150,000 more at the end of the current run of The Hunchback of Notre Dame. As a backdrop to all this, Jane Hermann, the New York agent for internationally renowned choreographer Christopher Wheeldon, said the company is in breach of contract with him.”
