Jon Keating, Raymond Van der Loos, Vladimir Vachel, Frank Hoekstra , Sven Lindemann & Peter Buci reveal influences, experiences and lessons to share from childhood to the highest positions of leadership and responsibility. Hosting every conversation is Callisto Grand CEO, Mark Harrison supported by Events Co-ordinator, Eszter Gabriel


Frank comes from a farming family background where his parents always encouraged him to enrol into higher education. He started his career at PwC as an auditor and today he is the CEO of a global organization with over 500 clients and 4 offices across the globe. The development pace of technology is moving rapidly and to become the best in class comes with sacrifices.
He motivates himself and his team by constantly challenging them, and his way of relaxing is through travel and sports.
