Stef is no longer with us: he died in April 2006 at the age of 48. But he lives in our practice. With a background in Physical Education (KUL) and Experiential Educatiion (MSU), Stef was the founder and inspiration for Exponent Challenge Services. His ever-lasting enthusiasm and dedication laid the foundation for Exponent's strong reputation among ropes course specialists worldwide today. The many terrific ropes courses that Stef designed and built throughout Europe and abroad, are a tangible reminder that he left us too early.
