Transforming Leadership with Evidence-Based Psychology for Sustainable Performance and Wellbeing
Without Marie's insight and input, I very much doubt that we would have got to where we are.
Empowering senior leaders and teams to drive systemic change through psychology-driven coaching.
High-performance environments demand leaders who inspire meaningful change, foster cultures of innovation and growth, and achieve lasting success. The Performance Equation partners with leaders, high-potential individuals, teams, and organisations to unlock their full potential through coaching and leadership development rooted in psychological science.
Our customised approach empowers leaders to excel while safeguarding their wellbeing, building resilient, high-performing teams, and cultivating cultures that deliver measurable, impactful results.
Drawing from evidence-based performance psychology, we work across sectors including the public sector, business, sport, and the performing arts, ensuring psychological wellbeing is at the heart of everything we do. Whether overcoming significant challenges or pursuing marginal gains, we help you gain the insight, skills, and strategies needed to achieve sustainable high performance.
Through tailored coaching, training, and consulting, we aim to equip you with the tools to thrive long after our work together concludes. Our goal? To leave you and your teams empowered, adaptable, and ready to navigate the complexities of the future with confidence.
The Performance Equation is a formula to help individuals, teams and organisations unlock their full potential and achieve their goals both personally and professionally. This approach to achieving success is based on Tim Gallwey's performance equation from his best selling book 'The Inner Game'
Performance =
potential minus interference
or
P=p-i
This method therefore involves working with clients on two main areas:
1. Realising potential
Grounded in positive psychology, we help people to gain insight in to their strengths, virtues and motivations, and to align them to their personal and/or organisational goals and values, galvanising flow,
2. Reducing interference
Grounded in performance psychology, we provide people with the knowledge, tools and techniques to manage internal or mental obstacles.
Marie was very personable and knowledgeable and I found the experience extremely enjoyable and productive.
What is the Performance Equation?

Thanks to our sessions I feel more in control, decisive and am actually able to visualise my 5 year plan and take the steps forward
Her affable relaxed approach helped me to open up and feel comfortable discussing my plans (and oftentimes neurosis!).
