Dylan Williams, its head of strategy, and Stephen Butler, a creative director, have been named partners of the London office. The pair will take equity in the agency.
It is the first time Mother has expanded its number of partners since the agency was originally founded. Williams, who joined Mother in 2005 following a stint at Grey, will take on the title of strategy partner. Meanwhile, Butler, a former Bartle Bogle Hegarty creative director who also joined in 2005, will take the role of creative partner.
Williams and Butler join Mother’s existing London partners: Mark Waites, Robert Saville, Matthew Clark, Andy Medd and Stef Calcraft. They will work alongside the partners of its Buenos Aires agency Madre, as well as Mother New York.
