Grossmann's professional career began in the Swedish Elite League during the 2003–04 season with Södertälje SK as a right wing. However, Grossmann only notched two career points in the SEL, both assists, over two seasons. Even so, he was drafted by the Dallas Stars in the 2004 NHL Entry Draft in the second round with the 56th overall pick.
Grossmann's professional debut in North America came on October 8, 2005, with Stars affililate the Iowa Stars. It was then that Grossmann was converted to a regular defenceman, a move that led to his being named Iowa's Most Improved Player after his rookie season.
Grossmann scored his first career NHL goal in a Western Conference Finals game against the Detroit Red Wings on a power play. In May 2008, he was given a new two-year deal of about $2 million to stay with the Dallas Stars.
Shortly after the trade on March 6, 2012, it was revealed that Grossmann had his name accidentally misspelled early in his pro career as "Grossman". He explained that he was young when the mistake was first made, and was so shy he never bothered to correct it. Thus all jerseys, trading cards, and rosters from his time in Elitserien with Södertälje SK and his NHL career with the Dallas Stars from the 2006-2012 seasons (as well as his first few games with the Flyers) have his name spelled incorrectly as "Grossman".
