In 1969, Muntz was born in
Voorschoten. As an amateur, he won three Dutch Amateur Championships and two Dutch Stroke Play Championships and became the first Dutchman to win
The Amateur Championship. He also represented the Netherlands in the
Eisenhower Trophy in 1990 and 1992 before quitting his law and psychology studies at
Leiden University to turn professional in 1993. Muntz began his career on the second tier
Challenge Tour in 1994, finishing 13th on the end of season rankings, and picking up his first title. At the end of that year, he qualified for the elite
European Tour for 1995 at final
qualifying school. Having had to return to qualifying school at the end of his rookie season, where he was again successful, he maintained his status on the tour through the 2004 season through his position on the Order of Merit. In 1999 Muntz came close to his first European Tour victory when he lost to
Warren Bennett in a play-off for the
Scottish PGA Championship. The following season he won the
Qatar Masters to become the first Dutchman to win a European Tour event since the tour was founded in 1972 and the first to win a top level European professional tournament since
Joop Rühl won the 1947
Dutch Open. Muntz has also played on the
Sunshine Tour and represented the Netherlands in the
WGC-World Cup in 1999. ==Amateur wins==
