Hans Bossenbroek

Human at Luminis

Hans Bossenbroek is one of the founders and Chief Executive of Luminis.

It may seem strange, but this coincides with his love for jazz music, diving and mountaineering. They all build upon the aptitude, discipline and persistence of the individual in a team.

This complex reality is aptly described by Neil Young: “It’s better to burn out than to fade away”.
