From January 2006 till October 2008 John worked for the Dutch Volleyball federation (NEVOBO). He became the first sitting volleyball coach working for NEVOBO, because NEVOBO took over the sport sitting volleyball from the Dutch Disabled Federation(nebasNSG) in 2006.

Despite many struggles with NEVOBO about the ignorance of sitting volleybal and organization issues, solutions were always found by his staff, without the players being negatively affected.

Many people still want to know more about this period, but John does not share these disappointing experiences in public. He believes that bringing enthusiastic and positive information is the best promotional tool for sitting volleyball.

This attitude has also made him one of the best performing head coaches of the NEVOBO since 1947.
