★ President
Chief Creative Officer
Liam is responsible for maintaining the high creative bar at DDB in not only Johannesburg but the rest of Africa as well. Having cut his teeth on global brands such as Guinness, Land Rover, Virgin Atlantic Airways and P&G he’s more than ready to once again take on his favourite challenge of building a network of strong creative thinkers, producing great results with great creative work.
Both in his own right as an art director and as the lead of several creative departments, Liam has collected an impressive array of Lions, Pencils and statues from international and local award shows. In his spare time he likes to chase a little white ball with a big stick around beautifully manicured lawns.
