Thirty years of helping people perform. Now, helping them recover from it.

I started out as a teacher and have spent the 26 years since coaching: as a hypnotherapist, as a breathing and sleep specialist, and for 17 years as Lead Learning and Performance Coach at Royal Marines Training Headquarters.

Teaching

I taught music first, which is where I learned to work one-to-one, then primary school, then as an area manager and trainer at a school for dyslexic adults. Being able to explain things clearly is still at the heart of everything I do.

Training

My foundation is clinical hypnotherapy, which I trained in with Randal Churchill and the late Ormond McGill. I went on to study CBT and Stoic philosophy with Donald Robertson, author of How to Think Like a Roman Emperor, Therapeutic Language Patterns with John Seymour, and respiratory physiology at the Buteyko Clinic International with Patrick McKeown, arguably the world’s leading expert on breathing pattern disorders.

The Royal Marines, 2006–2023

As Lead Learning and Performance Coach at Royal Marines Training Headquarters, working across the Ministry of Defence and other government agencies, I coached thousands of personnel: junior ranks, ship captains, submarine commanders, fighter pilots, nuclear engineers and brigadiers.

I taught on every leadership course from corporals to colonels, and spoke regularly at the Army Staff Leadership School, the Defence Academy and Britannia Royal Naval College. Those years also showed me, up close, what performing at that level for a long time costs people.

Private practice

Alongside the military I’ve worked with high street and investment banks, and kept a private practice with accomplished people across finance, sport, entertainment and entrepreneurship. What struck me is how alike it all is. A trader, a footballer and a submarine commander are under very different kinds of pressure, and it wears them down in much the same way.

What I learned

Working with people at the edges of what humans can do, I kept running into the same gap: most approaches skip the body. Breathing, sleep and how you eat shape how you see things, how motivated you feel, and how well you think and decide. My practice is built on that.

Outside the practice

I run a local Buteyko clinic on a pay-what-you-can basis and take on pro bono cases. I live in Devon with my wife and our three boys, and family life keeps teaching me about resilience and what matters, which finds its way into my work whether I mean it to or not.
