Two decades later the school programs have expanded considerably and also the locations, across Western Canada, USA, Norway

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 & Performance training. I want my students to gain valuable insights so they can achieve a greater potential either as a sport orthopedic specialists, surgeon, MD 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 and love cross-country mountain biking & trail running, backcountry skiing, skate skiing, training hard & well, pushing myself and exploring the unknown mentally & physically. With my racing background, mountaineering skills, knowledge of the human body and decades of training, I want to share and help athletes maximize their physical & mental potential.
