Reporting to Matt Waller, the executive creative director, Sloper will work across all BMB’s clients alongside Ben Lunt, the executive digital director.
Sloper joined CHI as the head of design in 2014 and worked on rebrands for clients including Argos, British Gas and TalkTalk.
She previously held the same position at BETC London as part of the Havas agency’s founding team in 2011. At BETC, Sloper worked on Bacardi’s global rebrand and Cockburn’s "pronounce responsibly" campaign, which was inducted into Campaign’s Outdoor Hall of Fame in 2011.
In 2014, Sloper was the foreman of the D&AD Craft in Advertising jury and sat on the black Pencils panel that year. She is the vice-chairman of the Typographic Circle, and has also worked at Bartle Bogle Hegarty, J Walter Thompson and M&C Saatchi.
Waller said: "Louise is a champion of creative and has a free remit to sprinkle her magic dust over everything that she sees."
