LONDON--Ketchum Pleon's UK digital head is departing after 18 months with the firm.

Mo Lishomwa will leave at the end of September. She arrived from advertising agency Saatchi & Saatchi in early 2011. A Ketchum spokesperson said that the company is currently searching for Lishomwa's replacement.

Meanwhile, Ketchum has hired Julie Dawson-Wills as its new head of content in the UK. Dawson-Wills joins from Edelman and succeeds Daisy Wallace, who left Ketchum earlier this year.

Dawson-Wills was an executive producer in Edelman's content team, and previously worked at the BBC and Wired.

“Julie brings a great combination of creative storytelling expertise through video and other visual media, as well as a proven track record of providing strong and strategic counsel to her clients about just how integral a role content plays in creating successful communications campaigns,” said Ketchum Pleon partner and managing director of client service Denise Kaufmann, to whom Dawson-Wills will report. 

Dawson-Wills will be responsible for developing storytelling solutions and overseeing end-to-end customised content creation for clients across the company’s integrated practice groups.
