About Duncan

I am a leadership and performance consultant, executive coach, and former professional footballer. Alongside my work with PEAK4, I help individuals, teams, and organisations build the conditions for sustainable high performance.

Having made more than 300 senior appearances for clubs including Sunderland, Middlesbrough, and Millwall, as well as representing England Under-21s, I experienced first-hand insight into the demands, pressures, and setbacks of performing in elite environments. Alongside my playing career, I earned a First Class degree in Economics and Business Management — becoming only the second player in history to achieve a First Class Honours degree while playing in the Premier League — before completing a Master’s with Distinction in International Business, Leadership and Management.

I believe sustainable performance is not achieved by continually pushing harder. It begins with greater self-awareness, intentional action and prioritising wellbeing. By creating the right conditions, individuals, teams and organisations can perform consistently, adapt to challenges and sustain success over the long term.
