Career
Pietersma"s first encounter with professional football was in the 2006-2007 season with NAC Breda. In 2007 he was convicted for burglary. Since then, he has been loaned out to Royal Bank of Canada Roosendaal the following season.
In July 2008, Pietersma was signed by Willem II, who were in the search for a third goalkeeper.
In 2009 he was once again loaned out to Royal Bank of Canada. In 2010 he played for Dijkse Boys until the club withdrew from the Topklasse because of financial reasons. In his last game against South Carolina Genemuiden Pietersma was shown the red card for a scandalous foul, which earned him a seven games suspension, because of "ernstig gemeen spel" (seriously mean play) as the KNVB stated.
