Callum is Programme Manager for the Diocese of Leeds’ award-winning music programme, a charitable initiative that brings sustainable music-making opportunities to around 7,500 children and young people in state schools across Yorkshire. He is also Operations Consultant for the National Schools Singing Programme, founded and supported by the Hamish Ogston Foundation, which is replicating the Diocese of Leeds model across the UK.


Callum was diagnosed with aplastic anaemia in 2020 whilst completing his degree in Economics at the University of Bristol. He received a stem cell transplant later that year and joined the AAT’s Youth Board – which he now chairs – whilst recovering. As a former patient, Callum is committed to supporting the AAT’s mission and ensuring fellow patients can access the support and treatment they need.
