The creative founders Malcolm Green and Gary Betts take on the role of joint executive creative directors to concentrate on overall creative strategy and new business.
They have promoted Steve Boswell and Steve Drysdale, the former D'Arcy deputy creative directors who joined DLKW in August last year, and Jon Elsom and Ken Sara to creative directors with day-to-day responsibility for running the creative department.
Green said: "The changes are both a reflection of the size and growth of the agency and the development, talent and maturity of the teams themselves.
To a degree, these steps will take Gary and myself in particular - and DLKW in general - out of the 'comfort zone'. I firmly believe that 2004 will be a hugely interesting year for the agency."
In addition, Susie Innes, a former board director at Grey who has worked on brands including Mars and Procter & Gamble, joins as the head of television.
The agency has also hired four senior creatives: Keith Terry from Saatchi & Saatchi; Rob Baker and Remco Graham from HHCL/Red Cell and Paul Hancock from DFGW.
