"My dream was to open a climbing gym in Valais."

What brought you to climbing?

I discovered climbing 15 years ago with a friend who introduced me to the sport. I took to it straight away, that feeling of being up very high and constantly having to find the right solution for the problem at hand. I am the kind of person who enjoys working on a tour: I don't get tired of constantly practicing the same section until the sequence flows perfectly.

Dreams and goals?
My dream was to open a climbing gym in Valais and I recently achieved this. Together with four friends, we opened a fantastic gym in Saxon with a surface area of 1,550 m2. It was a very labor intensive project, so I'm not tackling anything else right now, I simply want to enjoy this achievement.

My Top 3


• Motivation
• Energy
• Competition

Spectacular areas

• The "Cabane au Canada" in Rawyl (9a), that took me more than 70 attempts 
• "Van de panique", a route I opened near the camping ground in Van d'En Haut above Martigny, difficulty rating of 8c+ – so far, no-one has followed.


• I love small regional competitions in the group, with a great atmosphere and no stress. 
• I enjoy snowboarding
• I also like the finer things in life and love a good bottle of Bordeaux
