raffertyKetchum has elevated North American head Barri Rafferty to president of the firm, as CEO Rob Flaherty trades the president title for a chairman role.

Flaherty said Rafferty, a 22-year veteran and senior partner of the Omnicom firm, will help manage global growth of the firm and pursue new opportunities. Flaherty said she "embodies the future of our agency, and our industry."

Rafferty continues to oversee North American operations, as well as its digital and sports & entertainment units. She also oversees its Access Emanate, Capstrat, and Harrison & Shifman operations.

Ketchum earlier this year formed a 20-member leadership council and advisory board and moved chairman Ray Kotcher to a non-executive chairman role.
