Susan Gurley, executive director of the Association of Corporate Travel Executives, will step down on Dec. 1, announced ACTE president Richard Crum on Tuesday, during the association's global conference in Prague, Czech Republic. Gurley has accepted a position with a cause-based advocacy organization she declined to name. She will assist with the transition process until the end of the year; deputy executive director Megan Costello will serve as interim director until the board finds a replacement. The news comes a day after ACTE's announcement that BCD Travel sales executive Chris Crowley will become president-elect as of Jan. 1, 2010, and will succeed Richard Crum as president in May. Crowley, BCD's senior vice president sales, Europe, Middle East, Africa and Asia Pacific, will be ACTE's first European president. He has 18 years of experience in the travel industry and served as sales director for various hotel companies before joining BCD in 2005.
