All our practitioners bring a wealth of knowledge from their backgrounds in high performance sport, as well as coaching, communications, teaching, operations and sports science.
But our people are more than the sum of their job titles in high performance sport and business.
We are driven by the human first approach to helping people pursue their passions.

We curate the delivery of diverse talent and experience for your event, retreat, workshop or session.

Founder and Coach, Paradox Performance
Briony Fisher is a leadership and performance coach working at the intersection of systems psychodynamics, wellbeing and elite performance.
Her work is grounded in the belief that performance is shaped by the whole system; the physical, psychological, energetic and relational factors that influence both individuals and the environments they operate within.
Drawing on over a decade working in international crisis communications, alongside extensive experience working in wellbeing and the Premier League, Briony brings a unique lens to understanding the patterns, behaviours and dynamics that emerge in people and systems under pressure.
Her approach is rooted in the concept of paradox: that sustainable high performance is not created through choosing between results and humanity, strength and vulnerability, challenge and compassion but through learning to hold and integrate seemingly opposite concepts.
Briony has worked with CEOs, professional athletes, founders and leadership teams to navigate complexity, deepen self-awareness and develop the clarity, resilience and connection required to perform in demanding environments.
She creates non-judgemental spaces where individuals and teams can explore what may be limiting their potential, build greater capacity to sit with discomfort and cultivate a more embodied, purposeful approach to challenge.
Her work spans one-to-one coaching, team development and organisational consultancy, supporting people and systems to understand what drives performance, what disrupts it and what enables sustainable excellence.
