Lesley Bielby joined DiMassimo Goldstein as chief strategy officer. Most recently, Bielby was North American Head of strategic planning at Digitas and chief strategy officer at Hill Holliday. In addition, Tom Christmann joins the agency as chief creative officer, marking the first time that Mark DiMassimo will not hold that title. DiMassimo will still remain the agency's creative leader, guiding the creative direction of the agency and its client work. Lastly, Marc Lefton was named head of growth strategy and brand integration. As part of this hiring spree, Propolis, the brand consulting and research firm launched mid-2013 by both Bielby and DiMassimo Goldstein, will now merge into the DiMassimo Goldstein network, along with Mongo Industries, the talent consortium and idea development company founded and led by Christmann since 2010.
