Michael O’Brien, Ketchum’s president & global chief strategy officer, has joined 5WPR as global CEO.

Dara Busch, co-CEO, has exited to pursue new opportunities. Matt Caiola, co-CEO, is remaining at 5W, responsible for its corporate & technology communications practice.

O’Brien, who has counseled Wells Fargo, 3M and Tyson, spent 23 years at Ketchum in two different stints. He left his SVP—director of brand marketing practice job in 2004 after a seven-year run for Cohn & Wolfe’s NYC GM spot.

He returned to Ketchum in 2009. Prior to working at the Omnicom unit, O’Brien was director of global brand communications at MasterCard.

O’Brien will oversee 5W’s client services and operational departments, while counseling clients.

Ronn Torossian, 5WPR chairman/founder, said O’Brien “has a wonderful track record and will bring immediate value to the whole 5W family.”
