While working as Studbook Manager for the British Hanoverian Horse Society, Graham developed a fascination for seeing how far he could develop spreadsheets to work for him and improve the accuracy of the output. He joined Keens Shay Keens MK in 2006 specifically to be placed as an intern at one client. Having been given the sole responsibility for the accounting function he has managed to utilise his interest in spreadsheets to good effect, and takes great pride in the accuracy of the accounts produced. He maintains his interest in horse breeding but has little time for this since the arrival of his son in 2010. His family is now his major interest.
