Sébastien first skied when he was a young boy thanks to the help of his father who is also an instructor in the resort of Avoriaz. Once he felt like he was good enough, he enrolled in the ski club of Avoriaz. He then spent two years with the ISF before taking part in a few ski mountaineering competitions. For him, skiing is a very beautiful way to discover new mountains and it is also a good excuse to travel. Sebastien had the opportunity to teach how to ski in Chile, this experience allowed him to learn spanish and to ski on volcanoes. 

When he is not in the resort, he works as a mountain guide. His various hobbies include climbing, mountaineering, paragliding and agriculture. 

His favorite slope is the Crosats de la Chaux.
