The appointment is part of a move by Paul Twivy, the agency's recently hired chief strategic planning officer for EMEA and former Circus chairman, to bolster the region's planning department.
Chinn joins from his position as the director of planning, international business development at Saatchi & Saatchi, where he had worked closely with the worldwide chief executive, Kevin Roberts. Chinn had been at Saatchis since 1992 and had worked in the agency's New York and Los Angeles offices, as well as on projects across Europe and Asia. Between 1996 and 1998 he moved to TBWA/Chiat/ Day in Los Angeles.
Chinn said: "McCann is committed to having a very deep understanding of the client's business issues, so the creativity is actually rooted in an understanding of the realities of the business."
Twivy has also hired Philip Brown, with whom he worked at Circus, as a senior planner.
