Morgan Carroll will fill the dual roles of ECD and MD and report directly to DigitasLBi North America CEO Tony Weisman, effective immediately. In another change, SVP/group account director Jessica Henrichs will assume the duties previously handled by Chris Reed, who was EVP/head of account management for both the Chicago and San Francisco offices. "Anyone who has worked with Morgan has witnessed his collaborative disposition and determination," says Weisman in a statement. "This combined with his already admired leadership and feistiness to get great things done fast will serve Morgan well in his expanded and elevated role. I'm very excited to see his leadership evolve with the new opportunity in this role." Carroll effectively replaces Davin Power, who was appointed to serve as interim managing director of DigitasLBi Chicago in April after the agency promoted former Chicago/San Francisco president Doug Ryan to oversee the entire North American network.
