About Me

Scientific expertise

In order to always make the right decisions regarding your training, I am helped by the scientific approach that I have acquired in the study of sports and training science. As a sports scientist, I offer you a wide range of background knowledge.

Focus and motivate

Do the necessary work and after completing the possible you will, without realising achieve the impossible.

Personal Training

Two things are necessary for our work: indefatigable endurance and the willingness not to throw away something in which you have put a lot of time and work.


Since I can think, sport is my passion. With my studies for sports and applied training sciences, I put that dream into reality. I have been able to directly apply my knowledge from my studies, as a Professional athlete in skiing, as a passionate field hockey player, Boxer, runner and triathlete. These experiences are invaluable in my role as a personal coach.
