Guillaume has a lot of experience to his credit as a comedian, as much for advertisements like Maybelyne New-York, as for huge productions for Hollywood like White House Down, or for music videos for Céline Dion or Grégory Charles.

There is not one sport or physical activity that Guillaume misses. For him, being disciplined is a way of life, which is why he has been training since he was 18 years old.

In his free time, he also writes fiction. His passion for writing and his experience as a comedian allow him to analyse and to understand quickly what is expected from him during a photoshoot.
