John first worked as an academic, teaching psychology at Oxford University.  His career as an Advisor began in the UK Cabinet Office, where he was asked to devise some means of improving the quality of Cabinet Ministers’ decision-making.  Later projects have tended to be less ambitious.

Since founding Nicholson McBride Change in 1988, John and colleagues have helped more than 300 organisations across the world, in both the public and private sectors, to change the way in which they organise themselves and manage their people.

John studied psychology at Oxford University, where he also began his career, teaching and carrying out research into the origins of individual differences.
