QUALIFICATIONS
With over 25 years of experience in leadership development, operational excellence, and coaching, I’ve dedicated my career to supporting individuals and teams through transformative growth—both in the corporate boardroom and on the endurance sports field.
I began as a management consultant, guiding entrepreneurs and leaders of owner-led businesses to develop and execute bold growth strategies. Over time, my path evolved into internal consultancy roles within large, complex organisations, where I led strategic transformation and operational excellence initiatives. For over 16 years, I helped senior leaders and cross-functional teams enhance performance, navigate change, and deliver lasting results. In recent years, my focus has shifted more fully to executive and personal coaching. I now work primarily with senior leaders and aspiring executives to help them unlock clarity, navigate complexity, and lead with purpose. My approach draws on an evidence-based foundation—blending behavioural science, applied psychology, neuroscience, and mindfulness—to create practical, high-impact coaching relationships.
A distinctive aspect of my practice includes my work as an internal coach for Viasat and Inmarsat, leading providers of global satellite communications. In these roles, I supported leaders and teams through periods of significant organisational change and integration, helping to strengthen leadership alignment, enhance communication across functions, and build confidence in newly promoted managers. Operating in highly technical and complex environments, I focused on developing the human side of performance—enabling individuals to lead effectively through ambiguity, pace, and cross-cultural collaboration.
COACHING & DEVELOPMENT APPROACH
In parallel with my corporate coaching work, I’ve spent over two decades coaching triathletes and endurance athletes at both the club and individual level. As a British Triathlon Level 3 High Performing Coach and Hintsa Performance Coach, I bring a performance mindset to everything I do—helping people push their limits, sustain excellence, and thrive under pressure.
