Mortgage Specialist Manager

Affectionately known as ‘Little Jon’ by many of our lender partners, Jon has been part of the team since 2014. With experience of being a broker himself, he understands first-hand the challenges faced by our members. He loves finding solutions for brokers and clients who don’t believe that there is an answer to their problem. Away from work he can often be found walking up a mountain or by the sea, enjoying live music or shouting at the TV whilst watching sport.

James Ashworth

Senior Business Development Consultant

James’ passion and enthusiasm for the industry is evident from first contact, and consistent thereafter. In everything he does, he believes in challenging the norm and thinking differently. Dedicating his energy and skill to the client and their business, he challenges what is considered ‘standard service’ from a mortgage club. Music is central to James’ life – everything he does has a soundtrack – and he is a keen gym-goer on a mission to be in the best shape of his life so that he can keep on ‘living the dream’.
