A former member or the Swiss ski team he has developed to become an extreme skier who has many impressive descents to his credit. He has conquered many of the most challenging and difficult alpine routes in the Alps from the Ecrins to the Dolomites, and some big walls in the Yosemite.

After his first expedition on Alpamayo, he became fascinated by high altitudes which led him to take part in numerous expeditons. Olivier has successfully summited Pumori and Kilimandjaro. On two separate occasions he climbed, without bottled oxygen, close to the "Top of the World" by reaching 8300 m on the North Ridge of Everest. Alpine style and still without supplemental oxygen, he also summited four 8000 meters peaks: Dhaulagiri, Shishapangma, Hidden Peak and Gasherbrum II.

Join with Olivier and he will show you the magic and beauty of the high mountain country. Climbing, skiing or touring, whether you are a novice or experienced, a veritable cocktail of activities and destinations await you in the Alps and elsewhere.
