Kerstin Heffels has been active in the world of advertising and communication since 1987. She began her career as a booker for model agencies, then started out as an art buyer and developed her enthusiasm for film in the TV department of KNSK/BBDO in Hamburg. After working at Amirati Puris Lintas and FCB, she became Head of TV at D'Arcy, leading offices in Hamburg, Düsseldorf, Frankfurt and Munich.

Since 2004, Kerstin Heffels has been working exclusively with her husband Guido, who founded HEIMAT in 1999 (today HeimatTBWA) on various national and European clients, such as Hornbach, Audi, Burger King, Volkswagen, Rewe, Fonic (O2), and Swisscom.

For about the last 10 years she has been working solely and exclusively for the European communication of the DIY chain HORNBACH. Her award list is impressively long and had its highlight so far in winning the Cannes Grand Prix for Film Craft 2024 for the HORNBACH film ‘square meter’.

In 2025, Kerstin and her husband were honored by the German Art Directors Club for their joint lifetime achievement.
