KO Coca Cola Company

By Mike Esterl 

Wendy Clark, Coca-Cola Co.'s North American marketing chief, is leaving the beverage giant to head advertising agency DDB Worldwide's North American business.

DDB said the appointment is effective in January. Mark O'Brien, the current North American chief executive, will assume a new role as executive vice president at DDB's parent company, OmniCom Group.

Coke didn't immediately name a successor to Ms. Clark, who has held several senior marketing positions since joining the company in 2008.
