BOSTON Mark Wenneker, former group cd at Goodby, Silverstein & Partners, has joined Mullen as the No. 2 creative executive behind longtime CCO Edward Boches, who retains creative oversight and has no plan to leave the Interpublic Group agency.

Wenneker joins Mullen's headquarters in Wenham, Mass., as managing partner and ecd. He will oversee day-to-day creative initiatives at the shop and report to Boches.

"This is a chance to actually help shape an agency," Wenneker said. "Mullen has a vision, a management team and an entrepreneurial spirit that makes it an awfully desirable place for a creative person to work."

Boches told Adweek: "I'm focusing more on where we're going to navigate the agency [and] integration" of campaigns across all  media. "He's going to do the stuff I wish I still had time to do" in terms of leading creative teams in the approximately 180-person creative department. (Boches is only Mullen's second creative leader since the shop's 1970 formation, having succeeded Paul Silverman in 1998, not long before Mullen was acquired by IPG.)

Wenneker, most recently gcd at Omnicom Group's Goodby in San Francisco, has helped shape campaigns for clients such as Saturn, Hyundai, Comcast, HBO and Budweiser, among others. He served at the agency for nearly 10 years. Earlier in his career, he held posts at The Martin Agency and McCann Erickson, both units of IPG.

Key Mullen clients include General Motors, XM Satellite Radio, T.J. Maxx, Match.com, Ask.com, MassMutual and the Stanley Works, among others. The shop is preparing for a move next year into new office space in downtown Boston.
