Mathias David Grönberg (born 12 March 1970) is a
Swedish golfer.
Grönberg was born in Stockholm. He won the Swedish
Boys Championship in 1988 and the British Youths
Championship in 1990. That year he helped Sweden to
win the Eisenhower Trophy, and picked up the
individual title at that event.
Grönberg turned professional late in 1990. After
starting out on the second tier Challenge Tour, he
was a member of the European Tour from 1994 to 2003,
winning four European Tour events in that time. His
best finish on the European Tour Order of Merit was
tenth in 1998. However he was keen to join the PGA
Tour in America, repeatedly entering its Qualifying
Tournament. After six failed attempts he topped the
event in 2003. He had difficulty settling on the PGA
Tour, and after his 2005 second season he had to
return to the Qualifying Tournament to retain his
card, which he did.
