Beach Bits:
• In Nummerdor's first ever main draw match on the FIVB Tour, he and Richard Schuil defeated top-seeded Emanuel Rego and Ricardo Santos after advancing from the qualifier as the 36th seed.

Nummerdor represented Netherlands in the indoor Volleyball Olympic competitions at the 2000 and 2004 Summer Games where the Dutch National Team placed fifth in Sydney and ninth in Athens.  He started his Beach Volleyball career in 2006 with Richardo Schuil as the pair finished second on the European tour.  Nummerdor and Schuil captured one title (Valencia, Spain) while placing third twice with four "final four" placements in six events.

Nummerdor started playing Volleyball at the age of seven, but he marks the start of his real career from when he was 15.  “I finally began to grow a little so I could block for the first time,” he says.  It was a fine time for a kid who, as a setter for youth teams was often the smallest on the court.  Nummerdor finally grew to 1.94m and went on to become an outside hitter.  He played for the Dutch National Junior Team in 1993 and went to Athens in the summer of 1995 to compete in the European Championships.  A drop in form shut him out of selection for the Summer Olympics in Atlanta, a moment he describes as his biggest sporting disappointment. Two seasons with long time Dutch champions Piet Zoomers Dynamo put him back on track and he was again selected for the national side in 1997 when he was chosen as “Best Receiver” at the European Championships in the Netherlands as the Dutch captured the title.  Nummerdor also played in Italy.

Nummerdor was born in IJsselmuiden and currently resides in Uithoorn.  An only child, his parents are Henk Aart Nummerdor and Jannie Greving.

In their season-ending win in Sanya, the duo lost in the second round then won seven straight matches including five against top-10 seeded teams in claiming the gold. Nummerdor and Schuil ended the year as the fourth-ranked team on the FIVB Tour. They won their only CEV event, the European Championships.
2008: In 11 FIVB events Nummerdor and Schuil advanced to five semifinals and garnered two gold medals and two silver medals and ended as the fifth-ranked team in season points.
