Why Koen Gonnissen Book as a speaker ?

He shares his many years of experience during the training sessions and presentations. These training sessions are specifically designed to show the parallels between sport and business. Through a combination of academic models and practical examples from sports, Koen encourages individuals and teams to step out of their comfort zone, to think about their functioning and to achieve efficient and sustainable performances. Koen finds it a challenge to form a team from a group of individuals. With terms such as “What got us here, will not get us there” and “From a performance culture to a winning culture” Koen inspires in modern leadership.

Koen is an addition to every event

‘Koen knows as like no other how to personally address an audience. He does not speak in generalities, but tells relevant information about the (own) body and well-being. A valuable addition to which we have found a good connection with the central theme Survival of the Fittest.’
