Leo Burnett Names New Chief Strategy Officer

   Stephen Hahn-Griffiths is Leo Burnett Chicago’s new chief strategy officer. He fills the post vacated by Ben Kline, who left the Publicis Groupe agency last March.
   Hahn-Griffiths, 44, joins Burnett from Mullen, where he was managing partner and chief strategy officer. At Mullen, he helped win business like Zappos, Swiss Army and JetBlue. He has also worked at Doner, Grace & Rothschild and Saatchi & Saatchi.
“Stephen is a thought leader, a proven new-business winner, a complex-problem solver, a mature and established change agent and a very contemporary analytics and planning brain," Rich Stoddart, Leo Burnett’s North America president, said in a statement. “He is passionate about creativity and has been associated with great creative throughout his 20-year career, both in the U.S. and the U.K.”
Hahn-Griffith’s predecessor, Kline, joined Burnett as chief marketing officer in November 2003 from independent Wieden + Kennedy, where he was director of client services and led Nike’s global account during his six years at the Portland, Ore., agency. Kline’s departure was the latest change at the top of Burnett’s headquarters, where, in September 2009, Susan Credle, a 24-year veteran of Omnicom’s BBDO unit in New York, joined the agency as U.S. chief creative officer. www.adweek.com
