Sources familiar with the matter confirm that Allyson Witherspoon has left Kirshenbaum Bond Senecal + Partners. The exec spent the last four-and-a-half years at the agency and most recently held the title of group account director on BMW, specifically leading the automaker’s digital, social, emerging technology and CRM biz. The national creative account, of course, went into review back in March.

With Witherspoon out, we’re hearing stirrings from the grapevine that current KBS+P co-CCO Ed Brojerdi is stepping down and shifting posts at the agency to head of BMW North America’s account side–though our sources say that this is “absolutely not true.” Brojerdi oversaw creative for BMW’s Super Bowl work this year so he’s no stranger to the brand. Anyhow, we’ve been told that KBS+P is currently conducting a search to fill Witherspoon’s position so we’ll keep you posted when we find out who her successor is.
