Having skied for the first time at 3 years old and with his high ski level as well as his competitive expertise, Killian turned towards the profession of an instructor to share the experience he acquired after 15 years of competitions where he had the pride of being in the top 3 several times. He discovered the resort of Tignes Val Claret when he followed his father who had got a new job. 

For him, the practice of skiing makes it possible to enjoy an immense sensation of freedom and speed all while being in total control. Physical exercise is very important which is why he enjoys bodybuilding, cycling, running and playing football. 

His best teaching memory is one of a teenager who went from the beginner level to the class 3 level in just four days. His favourite slope is the Double M and he also mentions the stadium which he sees as a playground.
