Graduated from the National Comedy school in 2006, Guillaume has been evolving as a comedian for almost 20 years now. He has written and toured three shows (Cinglant, Trop humain, Du cœur au ventre), hosted galas (Just for Laughs), and won several awards (Olivier, Just for Laughs Revelation, Grand Rire). He is also a humorous columnist (ICI Première: Gravel le matin, Pénélope, De l’huile sur le feu) and sports commentator (BPM Sports, TVA Sports). As a creator and concept developer (Les 5 prochains, Le festival Dr. Mobilo Aquafest), he also hosts the podcast Wagner. As a writer, he contributed to the series Vestiaires (AMI-télé), but it is Libre dès maintenant (ICI TÉLÉ), his very first television series as both screenwriter and creator, that is now his greatest source of pride.
