OMD names new global chief operating officer

Omnicom Media Group agency OMD has named Ellen Griffin (pictured) as its global chief operating officer, marking a new chapter in the agency’s leadership strategy.

Griffin, who was previously global chief client solutions officer, steps into the newly created role with a remit to scale future-ready operating models across OMD’s global client base. She will report directly to George Manas, global CEO.

She first joined OMD in 2018 as global innovation director before moving into client solutions. During her tenure, Griffin led the evolution of OMD’s model, talent and capabilities, contributing to over US$2.5 billion in net new business wins. Her work included the development of bespoke solutions powered by Omni, Omnicom’s marketing intelligence platform.

“Earlier this year, OMD made a bold new promise: We create what’s next. With this new role, we’re delivering on that promise by building solutions that tap into Omnicom’s full advantage across media, data, CRM, commerce, content, and creativity," said Manas. 

He added, "Griffin brings the vision and operational leadership to help our clients win in an increasingly complex and challenging business environment."

Commenting on her new role, Griffin said, “In a time of accelerated disruption, even the most seasoned marketers are challenged to keep pace. This role is about accelerating and scaling transformation, ensuring OMD delivers the expertise, tools, and operating models that give our clients a competitive edge today and resilience for tomorrow.”

Her appointment follows a strong run for the agency, which was recently named media agency of record for Under Armour in Asia Pacific after a six-month pitch involving multiple holding groups.

Under the expanded remit, OMD will handle brand and performance media planning and buying across China, Korea, and South APAC, including Australia, Singapore, Malaysia, Thailand, and Hong Kong. This builds on an existing relationship that began in 2023, when OMD was appointed Under Armour’s media AOR for North America and EMEA.

During the pitch, OMD was recognised for its data-driven capabilities, leadership in China’s social and ecommerce space, and proven ability to integrate brand and performance within a single agency team. The win also reflects the strength of OMG’s agency-as-a-platform approach, enabling access to a network of specialist agencies across the Omnicom ecosystem.
