Born in Hilversum on 27 November 1961. The Ving Tsun Kung Fu school in Hilversum was established in 1981 by Gert-Jan, who, at this point, began as the instructor. Gert-Jan was teaching many years at various locations and eventually was able to set up his own location, which he specially arranged for Ving Tsun lessons. Via various instructors he came in contact with Wong Shun Leung in 1992. On Gert-Jan’s invitation, Wong Shun Leung gave his first training in The Netherlands. From 1992-1996 he trained in seminars conducted by Wong Shun Leung in both the Netherlands and Germany. Gert-Jan trained from 1994-2005 under Philipp Bayer in Germany, a student from Wong Shun Leung. Finally he established his own organization, the UVTKFS. Furthermore, he maintains contact with various trainers worldwide of Wong Shun Leung Ving Tsun, who openly and enthusiastically share information with each other.
