Ken Nolan has been appointed chief operating officer of WPP Media Ireland.
In the role, Nolan will have responsibility for the newly rebranded media company's agency brands, Mindshare, EssenceMediacom and Wavemaker.
Writing on LinkedIn, he said he would ensure WPP Media delivers "best-in-market offerings and consistency across all agency brands" to "unlock the true power of WPP for all our clients.
"This is more than a rebrand - it's a transformation. Here at WPP Media we are embracing the extraordinary."
Nolan joins WPP Media from Mindshare where he spent more than 17 years, serving most recently as chief operating officer with responsibility for day-to-day management of the company.
During his career, he has also held roles with Tricel and GT Media.
He graduated from what is now Munster Technological University in 2002 with a BCom in Business Studies (Marketing) and completed an MSc in Advertising at DIT.
Emma O'Doherty was recently appointed head of client leadership at WPP Media Ireland following 25 years with Mindshare.
Formerly known as GroupM, WPP manages more than $60bn in annual media investment and works with more than 75% of the world's leading advertisers in over 80 markets globally.
Announcing the rebrand last week, parent WPP said that WPP Media is connected to its wider global agency networks through WPP Open, its AI-enabled marketing system, which is backed by £300m in annual investment and partnerships with leading AI companies.
The group described WPP Open as the industry's most advanced platform for scaled and integrated creative, production, data, commerce and personalised media delivery services.

“Consumers already expect advertising to be relevant and engaging and buying experiences to be seamless; those expectations are only going to accelerate in the age of AI," said Brian Lesser, CEO of WPP Media.
"WPP Media is built for a world in which media is everywhere and in everything.
"By investing in our AI-powered product, integrating our offer with data and technology, and equipping our people with future-facing skills, we’re helping our clients to stay ahead of rapidly changing consumer behaviour and unlock the limitless opportunities for growth that AI will create.”
