My Story

Hi, I’m Gill Thackray. My journey into the world of sustainable performance, change processes & wellbeing began whilst working in United Nations refugee camps.

Despite the traumatic events that had forced the people I worked with to leave their homes, their resilience was evidenced everywhere. What I was observing was the epitome of resilience, post traumatic growth. A counterintuitive response to trauma where human beings thrive.

Since then I’ve been working as a performance psychologist with Fortune 100 Companies, elite sporting bodies like UK Sport, the Football Association and the medical profession, non profits, small businesses & youth leadership organizations across the globe using evidence based strategies to create sustainable high performance individuals, teams and organisations. Change is a constant, it’s how we move through it that makes the difference.

I work internationally with individuals and businesses using data driven performance psychology strategies, teaching people to optimise their professional lives and their personal lives.

I work with some amazing companies, universities and organisations from tech start ups to established fortune 100s including

I’ve loved every minute of helping these organisations to optimise their performance, develop their leadership and build their resilience & wellbeing.

I consult, coach, train, speak at events & facilitate leader retreats. I’ve lectured in performance psychology & in 2016 I was invited to be Visiting Professor at CHE in Cambodia. I leverage my corporate and international experience to package the latest research in psychology, resilience, mindset and sustainable performance into something practical that works.
