JWT Combines California Offices

The decision by J. Walter Thompson to link its two California offices under the JWT West banner and a single management structure has triggered a shuffling of some creative talent.

Mike Mazza, formerly gcd at Publicis Groupe’s Publicis & Hal Riney in San Francisco, joins JWT West as ecd on June 1. Mazza, 46, started at Riney in 1997, working on Sprint PCS and Jamba Juice. He will be based in San Francisco.

To replace Mazza, Riney last week said it was hiring svp and gcd Jon Soto, 42, most recently an art director at Omnicom Group’s Goodby, Silverstein & Partners in San Francisco.
