Welcome to spring, the season for hiring new planning chiefs.
Following today's departure of chief creative officer Aaron Griffiths, the New York office of Arnold will no longer have a CCO.
JWT, amid the exit of North American CEO Peter Sherman, is expanding its leadership team in New York. Lynn Power, former president of Arnold in New York, is joining the WPP Group agency as managing director. As such, she'll share responsibilities with the current managing director, Claire Capeci. Both will report to new global president Gustavo Martinez.
