In 1998, he won the Welsh National Over 40s snooker championship. He continued to excel in Welsh local amateur snooker events until his sixties.
 He was known to have had a solid gameplan and solid allround game. However, he had not competed at the professional circuit due to his anxiety and homesick issues. He remained as an amateur player until the end of his career.
 He was married and had two sons and a daughter. He was diagnosed with leukaemia in April 1999 and died on 8 May 1999 at the age of 63 in Pen-y-graig.
