This week, a couple of tipsters asked, “Why is Tom Christmann no longer at JWT?” Well, here’s your answer, we think, and it’s become an all-too-familiar one. According to sources  familiar with the matter, Christmann left JWT New York a few weeks back to, yes, go freelance (he’s now attached to Montague/Ryan’s Co collective). We’ve been told that the parting was “totally” amicable. Christmann, to refresh your memory, joined JWT NY in May 2009 from the now-defunct Cliff Freeman & Partners, where he spent about 18 months as the top creative executive after Freeman himself. Some of his last projects as an ECD at JWT included the Stride “Chase” work starring Shaun White. During his career, Christmann has held CD jobs everywhere from TAXI to KBS+P to BBDO.
