Founder/Director of the X-Training School
To inspire, educate and share my passions is the foundation of my work.
I’m committed to my profession as a consultant, author, speaker and education provider in the field of Sports rehabilitation and Performance. I want my students to gain valuable insights so they can achieve a greater potential either as a sport medical expert, physiotherapist, or sport specific coach, I find it extremely nourishing.

I thrive for excellence and set high standards towards the material I write and teach. The human body fascinates me, I always aim to translate the complexity of human function into progressive and highly effective performance enhancement techniques and rehabilitation & injury prevention applications.

I’m a passionate mountain athlete from mountain biking, running and ski mountaineering. With my background of racing, mountaineering skills, knowledge of the human body and three decades of training I can share and help mountain athletes maximize training, performance and acquire new skills with the programs i offer at the Chamonix mountain endurance academy.
