GolinHarris CEO and President Fred Cook discusses the firm’s new G4 model called Prevolve and the factors that led to the restructuring of the agency. “We’re breaking away from traditional agency silos,” Cook said in announcing the new model. “We’ve replaced the standard, seniority-based hierarchy with global teams of dedicated specialists who are embedded in every account. As our world evolves, so, too, do the needs of our clients. Now, more than ever, clients value smart people who can provide actionable insights into their business.”
