In his new position, Madden will run the planning department alongside Lazar Dzamic. The pair will split the role of planning director, with Madden taking on responsibility for the brand and direct marketing planning strategy, and Dzamic focusing on the agency's digital planning strategy.
The appointment is the latest in a series of senior appointments at Kitcatt Nohr. Two weeks ago, it hired Phil Keevil as its creative director. In June, Chris Cowpe joined as a non-executive director, and Huw Davis joined as the data director in March.
Marc Nohr, a managing partner at Kitcatt Nohr, said: "This is a real coup for the agency. We've wanted to tempt Richard over here ever since we launched."
Before Claydon Heeley, Madden, a copywriter-turned-planner, was the planning director of Tequila\London, a role he resigned in autumn last year.
