December 16, 2009 – Executive search firm Gundersen Partners has appointed Sarah Thewlis as managing director of the London offices. This planned step has been advanced following the sudden death of her predecessor, Tony Bucher; it was always the intention that Ms. Thewlis would take over in 2010 when Mr. Bucher was to become chairman of the U.K. Group. Ms. Thewlis brings a wealth of varied experience to her role, having previously held senior leadership positions in both the public and private sectors. “Tony was an outstanding search professional, but more than that he was a staunch friend who made a huge impact upon the lives of many,” said Peter Fitzpatrick, president of Gundersen Partners. “In Sarah we have a seasoned executive who had already assumed many of the managerial responsibilities of our U.K./European business. We have the fullest confidence in her as she continues to build this important geography.” Gundersen Partners recruits at chief executive, director and senior manager level in the commercial and not for profit sectors.
