Graeme joins from Mother, where she was the head of business development. She will be reunited with the Grey chief executive, Chris Hirst, with whom she worked at Fallon ten years ago while an account director on clients such as Sony Electronics, the BBC and Skoda.
Reporting directly to Hirst, she will handle accounts including Vodafone Ireland and focus on business development across existing clients.
Hirst said: "Natalie’s appointment completes a series of important hires for the agency in 2012 that have spanned account management, creative and planning."
Graeme added: "Grey is quite simply a great agency backed by one of the best networks in the world, where creative innovation and business acumen are valued."
