Harris Diamond, CEO of McCann, retires and fingers over the reins to COO Invoice Kolb
Harris Diamond, Chairman and CEO, will retire later this year after leading the McCann Worldgroup for nearly a decade.
Bill Kolb, who was named Chief Operating Officer of the global agency network earlier this year, will succeed Diamond.
Kolb is a McCann veteran who has held a number of positions within IPG's own network during his career. Prior to becoming chief operating officer, he was global president of diversified agencies at McCann and chairman and CEO of Commonwealth // McCann, the agency of the network dedicated to Chevrolet.
Previously, he held a number of executive positions at MRM and Momentum, both agencies under the McCann umbrella.
"Bill understands our customers' business needs across a range of industries, disciplines and regions," said Michael Roth, chairman and CEO of IPG, in a statement. “Bill's long and successful history at McCann spans two decades and positions him in a unique way to develop the world group model for the future. With Harris' transition support, we are confident that the company can continue to realize its vision of being the world's leading organization for creative marketing services. "
Under Harris's leadership, McCann has honed his creative skills and has received a number of awards. In 2019, McCann received industry awards ranging from Cannes Network of the Year to Most Creative Agency Network in the Effie Index. It was also named Adweek's Global Agency of the Year in 2019. McCann's main customers include Microsoft, Verizon and L’Oréal.
Harris has been with IPG for much of his career. Prior to joining McCann, he was CEO of Weber Shandwick PR firm and the Constituency Management Group (CMG), a collection of agencies.
“After 35 years of building a PR business and leading multiple global marketing communications networks at IPG, it is time for me to explore new horizons. I'm proud of everything the McCann Worldgroup team has achieved and I'm delighted that Bill is taking the reins from McCann and driving us forward. “Said Diamond in a statement. "I am deeply indebted to so many customers and colleagues, particularly the McCann Worldgroup senior teams, Weber Shandwick, CMG and IPG who, to the extent that I have been successful, have been truly key to that success."
