In 2011, Porter Novelli acquired Silicon Valley-based Voce Communications. That same year, several senior executives left the firm, including its global digital director, director of global health and regulatory affairs, executive VP for strategic planning and research, senior VP for global digital and PR and its executive VPs for global content director and social media. Departures continued in 2012 with departures of Stockman, the CFO, the chief marketing officer, and the president. Karen van Bergen was selected as the new CEO in December 2012. Brad MacAfee then became CEO in February 2016, when van Bergen rose to the role of CEO of parent Omnicom Public Relations Group.
