The new office is to be headed by Emily Urban-Smith, former account manager at Red Consultancy and director of Urban Mole Consultancy, who has worked on major clients including Boots, Coca-Cola and GlaxoSmithKline. She has worked for Leigh as a consultant previously.
The new office follows account wins involving firms based in northern England, including Macclesfield-based sports nutrition brand Monkey Nutrition and Newcastle-based online fundraising platform Givey.
Urban-Smith said: "Having worked with Rich before and knowing he wanted to expand, Manchester seemed the perfect place to help grow the agency and take advantage of new opportunities."
Leigh said: "With clients already in the North, I can’t think of anybody better placed to help us take advantage of the opportunity I see to grow the agency."
The agency's other clients include estate agent Hanover West End.
