FORT WORTH — Texas Ballet Theater Managing Director Margo McCann no longer works for the company, a spokeswoman for the company confirmed Monday.“Margo is no longer with the organization, and Texas Ballet Theater does not discuss personnel issues,” Jamie Brown, who manages TBT’s public relations, wrote in response to an email from the Star-Telegram seeking more information Monday. McCann could not be reached for comment Monday. Brown said Terri Sexton, TBT director of development, is serving as interim managing director.By Monday evening, Sexton’s name and contact information had replaced McCann’s on the TBT website, and a call to the managing director’s phone number went to Sexton’s voice mail.McCann had served as managing director since March 2009; she held the position on an interim basis for six months before her full-time appointment and presided over daily operations during a tumultuous period in which the financially strapped company had to raise large amounts of emergency funding or face the possibility of shutting down.Things seem to be turning around for the company. A production of Swan Lake next month will feature live accompaniment by the Fort Worth Symphony Orchestra for the first time since the company began using recorded music as a cost-cutting measure in the 2009-10 season. The orchestra will acompany two TBT ballets next season.The company was scheduled to announce its 2014-15 season with a free public dance performance on the outdoor stage in Sundance Square at 11:30 a.m. Tuesday.
