Tim O'Keeffe, GM and senior managing director of tech shop Horn, has moved to FleishmanHillard to serve as San Francisco general manager.
J.J. Carter, GM of San Francisco for the past three years for FH, was elevated to president of the firm's Western region in 2011.
San Francisco is the Omnicom unit's largest West Coast office, trumping Sacramento, Los Angeles, San Diego and Orange County (Irvine).
O'Keeffe, who was at FH earlier in his career, exits Horn after two years. He was a senior VP at Hill+Knowlton Strategies and earlier did a stint at Ruder Finn before starting out at Horn.
FH also upped Vanessa Yanez to head its San Francisco tech team under O'Keeffe. She joined in 2011 from Axicom.
