Garth Miller knows what it means to lead when the margin for error is zero.

 

He’s commanded troops on operations in hostile environments, managed risk in one of the world’s most safety-critical industries, and led a team to the summit of Mount Everest.

​

A former British Army Major, Special Forces veteran and now a captain with a major UK airline, Garth draws from a lifetime of operating in environments where composure — or the loss of it — can mean life or death. He works with organisations that want practical tools for leading under pressure, managing risk, and building teams capable of performing when conditions are far from perfect.

​

In May 2025, he led a team of former Special Forces soldiers on a record-breaking speed ascent of Everest — summiting the mountain six days and thirteen hours door-to-door from London. The expedition made headlines around the world, cutting a process that normally takes two months down to less than a week.

​

It was a real-world test of innovation, disciplined preparation and courage. For Garth, it was never about records. It was about setting a goal that looked impossible, then building the plan, the people and the mindset to make it possible.

​

His delivery is direct and engaging. His stories are lived. Audiences leave with a sharper sense of what high performance looks like in practice — and what it takes to hold their nerve when pressure begins to rise.
