His appointment is part of a senior-level restructure at O&M. Russell will work as one of a new group of creative partners, alongside Derek Lewis and two other partners yet to be appointed.
Russell has worked for Wieden & Kennedy since 2000, moving from the London agency to the Amsterdam office earlier this year. During his London stint, Russell penned the "grrr" spot for Honda Diesel.
Poynton said: "We're obviously excited Richard is coming on board, especially in light of his history of fine work, not least his most recent Honda Diesel spot. He is going to add a wealth of experience to our department."
Russell started his career as a junior copywriter at Boase Massimi Pollitt in 1985, working for clients such as Channel 4, Clarks and Knorr. In 1987, he embarked on an eight-year stint at Leo Burnett, eventually gaining a seat on the board.
After a brief stint at Bates Dorland, he spent three years as a group head at D'Arcy Masius Benton & Bowles.
During his career, Russell has won a gold at Cannes for McDonald's work and a silver for poster work for Gordon's Gin, plus several Creative Circle and D&AD accolades.
