Paul Sincoff, the man behind the “Ad Agency in My Mind” blog, has left Mullen’s Boston office after just seven months. During his brief stint, Sincoff served as SVP/ACD on JetBlue among other clients. Prior to joining Mullen, Sincoff spent four years give or take as a copywriter at TBWA\Chiat\Day and one as an interactive CW at TBWA\Tequila, where he worked on accounts ranging from Activision and Playstation to Pepsi and Visa.

From what we’ve been told, Sincoff is heading to Europe for a while before returning to his West Coast stomping grounds to freelance.
