Saatchi & Saatchi is changing CEOs in New York again, after just 14 months.
CEO Durk Barnhill is being replaced by Brent Smart, a worldwide managing director on General Mills, a key agency account.
Barnhill, in turn, is shifting to business development director, a new position. In particular, he'll focus on expanding the Publicis Groupe shop's digital capacity, according to Saatchi.
For now at least, Smart, 39, will retain his role on General Mills, the second biggest account in New York after Procter & Gamble and the third largest client worldwide, after P&G and Toyota.
In appointing Smart, worldwide CEO Kevin Roberts cited his track record as an "outstanding agency leader, a strategic and eloquent contributor in our boardroom and a fearless producer of work that is equally creative and commercial."
The rapid turnover in the top job follows years of stability. Before Barnhill arrived, in September 2012, Mary Baglivo had been office CEO for nearly eight years.
Smart has worked at Saatchi since December 2011. Before that, he was a managing director at BBDO in San Francisco.
