« In my opinion, Guibert possesses a multi-dimensional vision of reality. He plays with complexity, and transforms it into a strategic vision to resolve the most acute issues encountered in business. The key words of his culture are expertise, optimism, solidarity, sharing, interaction. He is a very popular conference speaker who speaks with his public rather than in front of them. »
