Michael Wall, who stepped down as the global chief executive of Lowe and Partners last week, is joining Mother as an equity partner. Wall, who was a founder of Fallon in 1998, will take on the new position of global chief executive at Mother, working alongside the partners of Mother Holdings. During Wall’s time at Fallon, the shop created work for brands including Sony Bravia, Skoda and Cadbury. Following a hiatus after Fallon’s sale to Publicis Groupe, Wall took charge of Lowe and Partners in 2009.
