Rhea will leave the firm, which was bought by Added Value in 2007, at the beginning of January to “pursue his passion for organisational consulting”.

Jonathan Hall (pictured), who currently heads Added Value’s Paris office, will move across the Atlantic and take the role of executive vice president and managing director of Cheskin Added Value. He will also be given responsibility for leading Added Value’s North American brand strategy and innovation practice.

Hall joined Added Value in 2005 as global client managing director before being given responsibility for the firm’s French arm in 2008.

Maggie Taylor, North America CEO, said: “We look forward to our relationship evolving as Darrel begins his new endeavour, and we’re extremely fortunate that Jonathan will bring his extraordinary intellect, creativity and business savvy to our group.
