We’ve received confirmation that Alison Grippo has taken over as managing director of Huge’s San Francisco office, which she helped get up and running over the last year and now boasts a headcount of 30 staffers along with clients like Twitter and HomeAdvisor. Grippo, who has been with Huge since 2010 and also helped set up the IPG-owned digital agency’s London office, succeeds Wing Pepper in San Francisco.

From what we’ve been told, Pepper is taking a break from the agency world after twenty years and is planning on starting up his own operation. For the time being, though, he’s still consulting at Huge, where he’s spent the last two-and-a-half years, and helping out with Grippo’s transition. Prior to Huge, Pepper spent several years as an EVP on the account/digital side at MRM. As for Grippo, the new San Francisco MD most recently served as global director of program management and delivery. During her career, the exec has also worked at the likes of iCrossing and Razorfish.
