Mark Howley promoted to ZenithOptimedia UK CEO

ZenithOptimedia’s managing director Mark Howley is to replace current UK CEO, Grant Millar, who will take up the newly created role of chief client officer, ZenithOptimedia Worldwide.

Both reporting to Belinda Rowe, global managing partner and UK chairman, the moves form part of a wider senior restructure at the UK agency.

“Driving business growth is a primary focus for ZenithOptimedia and these promotions are part of this global programme,” said Rowe.

“I am absolutely delighted that Grant is able to build on his success at ZenithOptimedia UK by taking on this critical role in Worldwide.

“Mark’s promotion to UK CEO is also richly deserved. He has done fantastic work over the past couple of years building relationships with clients such as Aviva and Nestlé and taking charge of the operational running of the business.”
