David started swimming at his local swimming club in Barry, South Wales, when he was seven years of age. A year later he joined his current club, The City of Cardiff, and he has been coached by Haller since 2000. Before this, he was coached by Haller's assistant, John Stow.
His first sporting success was winning the Welsh Age Group Champion Under 11s in 1996 - he went on to make his first Great Britain team in 2002.
At the World Championships in 2005 and the Athens Olympics in 2004, David finished third behind Australian Grant Hackett and American Larsen Jensen - who both will miss the 2006 Commonwealth Games - in the 1500m Freestyle.
He was voted in third place of the The Welsh Personality of the Year Awards by the public after his Olympic performance in 2004.
His training regime is intense - he is in the pool six days a week, mostly twice a day, and in his little spare time he enjoys watching football and rugby and he supports Cardiff FC.
