David Cresswell
Headmaster
Growing up around the world as the son of a Foreign Office diplomat, I developed a deep appreciation for different cultures and a love of languages, shaped by classrooms full of diverse nationalities.
I returned to the UK for boarding school, arriving as a keen sportsman and leaving as a Drama Scholar. I read Modern Languages at Oxford University, where I captained the Men’s Hockey team in the Varsity Match (despite defeat to Cambridge!). I began teaching at Cranleigh School, later becoming Head of German and a Deputy Housemaster at Radley College, where I also coached the 1st XI hockey and led the tennis programme.
After a spell as Head of Sixth Form at Barnard Castle School, I became Senior Deputy Headmaster at Whitgift School in London before returning to Barney as Headmaster. My wife is a local GP, and our children are proud members of the Prep School. Inspired by my own teachers, I believe in weaving ambition, positivity and a growth mindset into school life.
