At the heart of the leadership team is a genuine love of skiing, including all aspects of the sport – doing it, learning it, teaching it. But it's not just about passion. We're a curious and hard working bunch, with mountains of experience and extensive industry knowledge and relationships. Our diverse collective experience – spanning decades in education development, teaching, scientific study, and executive resort leadership – positions us at the forefront of ski professional training and development. Each member brings their own story, expertise, and dedication to the sport.
