Omnicom Media Group (OMG) has named Philippa Brown CEO of PHD worldwide.

Brown, who joins PHD from her role as CEO of Omnicom Media Group UK, succeeds Mike Cooper, who was recently named group CEO, Omnicom Media Group APAC and EMEA.

Omnicom Media Group CEO Daryl Simm said: “Philippa is a proven leader and a natural fit to lead PHD globally.

“As CEO of OMG UK, she has worked closely with Mike Cooper in the original positioning of PHD as a global network and has been heavily involved in PHD’s international client successes.

“She has singular insight into PHD’s culture, the expectations that clients have of the agency, and the ongoing transformation required for success.”

Prior to joining OMG, Brown spent 10 years at IPC Media, rising to board director.

Her previous experience also includes stints at full-service DMB&B and BBH.

She is known across the industry for her skill in building enduring client relationships as well as her commitment to creating a learning culture that attracts and retains talent.

Commenting on her new role, Brown said: “Over the past decade, PHD has become one of the most respected agency networks in the industry.

“It’s growth, thought leadership and award-winning work is a testament to Mike Cooper’s leadership, and the combined contributions of our many talented people all around the world.
