Andy Main, global chief at Deloitte Digital, will be the new CEO of Ogilvy, taking over for John Seifert, who announced his plan to step down in April.
Mark Read, CEO of WPP, said Main "has demonstrated the effectiveness of blending creative, technology and consulting services."
He said Main's "belief in the power of creativity to transform businesses and the importance of people and culture in organizations aligns closely with our vision for WPP and our agencies."
Main began his 25-year career at Andersen Consulting and moved to Deloitte Consulting in 1999 as a principal in the high-tech practice. He took over the chief digital spot in 2014.
He called the Ogilvy brand synonymous with creative and strategic excellence "We have a great opportunity to help clients deliver sustainable growth by using Ogilvy’s creative genius to transform not only brands but entire businesses," he said.
Seifert began his Ogilvy career in 1979 as an intern in Los Angeles.
