Crispin Porter + Bogusky’s L.A. office continues to grow out its creative department as we’ve received confirmation that creative director Ryan Jacobs is headed over to said agency from Saatchi & Saatchi LA. Jacobs was a principal/CD at Mint Design before freelancing at Goodby then eventually heading over to Saatchi LA to take a CD post under Mike McKay in 2008. At CP+B, Jacobs will serve as a creative director on the Old Navy account and work on new business.

CP+B ECD Tiff Rolfe comments, “We’re excited to have Ryan as part of the new LA team,” said Tiff Rolfe, VP executive creative director at CP+B. “His design background and rebranding experience will add a great asset to our team for our current brands and new client initiatives.”

From what we hear, though, Jacobs isn’t the only S&S defection this week as ACD Matt Titone has apparently split for B-Reel while art director Michael Gurman has moved up the coast to take a gig at AKQA. We’re double-checking with our sources on this, but three creative defections at one time does raise some eyebrows, though S&S has given us drunken egg nog/beer pong holiday hijinks and the occasional Prius campaign.
