It appears that Mike Dennelly‘s on-again, off-again relationship with G2 is back on again as sources tell us that Dennelly has rejoined the agency and starts today. Dennelly left G2 (again) last September for McGarryBowen and a gig at said agency’s Digital Lab.

With Wendy Lurrie now out at G2, spies say Dennelly felt more “comfortable” in returning to the fold (or maybe it was just that MB wasn’t the right fit) and in doing so, will once again report to Eric Pakurar, who joined as head of U.S. head of strategy/planning. We’re double checking with G2 to find out what Dennelly’s exact title is.

Update: Dennelly has joined G2 as executive director, digital strategy.
