New York’s City Opera has elevated its development director to the post of executive director. Jane Gullong’s ascension displaces Sherwin Goldman, who will remain with the company and dedicate himself full-time to the daunting task of finding the company a new home. City Opera had hoped to be the anchoring arts tenant of the new Freedom Tower at Ground Zero, but its application was turned down. The company is denying rumors that Goldman was forced out of the top job by the board.
