(SGI) On July 31, after almost 30 years, Markus Bötsch will leave Jack Wolfskin, the German outdoor brand acquired by Callaway Golf at the beginning of last year. Bötsch is currently a member of the management board, responsible for sales strategies. He started out as a sales assistant in 1991, then became a sales representative and, after various management positions in sales, finally became chief sales officer in 2007. Jack Wolfskin’s chief executive, Melody Harris-Jensbach, has not yet named a successor for Bötsch. It was only in July of last year that another top executive of the company responsible for finance and operations, Jörg Wahler, resigned. Ante Franicevic was then appointed chief financial officer, followed in the autumn by Alexander Hauser as the new chief operating officer.
