Mark Gallagher, founder and senior partner at Pagefield, said: "Alan is a truly outstanding individual: a champion athlete, a great business success and a delightful man. Having worked with him for more than a decade, I couldn’t be happier that he’s now joined team Pagefield."
Pascoe said: "Having enjoyed creating and building top-performing agencies for most of my working life, I am so pleased to be joining Mark Gallagher and his team at this crucial point in Pagefield’s development. I look forward to helping Pagefield here and abroad, and doing some exciting work together."
