In Kallman's one campaign at Creighton he started 17 of the 23 matches he played in, helping to anchor a stingy Bluejay defense.
He played every minute in the playoffs where Minnesota Stars FC won the club's first NASL Soccer Bowl Championship.
In 2012, Kallman was a key part of the Minnesota defense during its second straight trip to the NASL Soccer Bowl.
Kallman's brother Brent played at Creighton University before turning professional for Minnesota United FC.
His sister, Kassey, plays professionally as well, and has represented the US national team at the youth level.
