Diss, who was also the creative chief at Billington Cartmell, will head up a team of ten responsible for FMCG accounts including Sol, Britvic and Kerry Foods. He reports to the executive creative director, Graham Wall.
Before Billington Cartmell, Diss was an art director at Wunderman, where he was part of the team that created the "help the oversharers" campaign for Pringles.
The Marketing Store has also hired the creative team Ben Drummond and Tristan Hyatt-Williams from Publicis Chemistry. Drummond joins as a senior art director and Hyatt-Williams as a senior copywriter.
The pair previously worked at WCRS, Leo Burnett and Iris. They won The Impossible Brief project launched by BBR Saatchi & Saatchi at the 2010 Cannes Lions International Festival of Creativity with their "blood relations" campaign.
The duo will report to Diss and work across accounts including Britvic and Heineken, as well as a number of new-business initiatives.
