Omnicom Media taps Ellen Griffin as OMD global brand president

United States –  Omnicom Media has appointed Ellen Griffin as the new global brand president of OMD, the world’s largest media agency network. The move, effective immediately, follows the recent naming of Bradley Rogers as CEO of OMD USA.

Griffin previously served as the agency’s president and global chief operating officer. In her new capacity, she will oversee global strategy, capabilities, and service solutions.  

She joined OMD in 2018 as global innovation director. During her tenure as global chief client solutions officer, she worked on bespoke client solutions integrated with the Omni intelligence platform.

Griffin will succeed George Manas, who has transitioned to a role at parent company Omnicom as chief growth and solutions officer.

Florian Adamski, CEO of Omnicom Media, credited the outgoing president with strengthening the agency’s market position. “George has been an exceptional steward of the OMD brand over the past four years,” Adamski said.

Adamski continued, “As the orchestrators of client success, our agencies need true practitioner-leaders – executives who have worked side-by-side with marketers as they navigate an increasingly challenging marketplace and know how to connect the full spectrum of Omnicom marketing capabilities needed to drive outsize growth.”

He added, “Ellen exemplifies that model. She brings deep experience leading marketing transformation for clients, including Clorox, McDonald’s, and PepsiCo, and she will ensure that OMD agencies around the world fully leverage Omnicom Media’s market-leading strengths in scale, data, identity, commerce, and talent to unlock growth for our clients.”

Moreover, the leadership change comes as the industry grapples with rapid shifts in AI, commerce, and platform evolution. Griffin noted the importance of navigating these complexities for partners.

“In this environment, clients need partners who help them navigate not only the challenges they see, but the ones they do not yet recognize,” Griffin highlighted. 

“OMD plays a critical role in helping clients move through this complexity. By connecting insights, platforms, data, and media strategy, we help clients anticipate change, unlock new opportunities for growth, and act with confidence in an increasingly dynamic landscape. My priority is ensuring our teams feel empowered, connected, and equipped to deliver exceptional results for their clients every day.”
