A three-time singles and doubles All-American, Dorsch won the Intercollegiate Tennis Association Player of the Year award in 2004 and 2005. He was the NCAA Division 1 singles champion in his final year. The German then committed himself to the international tennis circuit.
He has only been able to qualify once for the main draw of a Grand Slam tournament once, which was at the 2006 Wimbledon Championships. In the opening round he faced former Wimbledon semi-finalist Xavier Malisse, who won in straight sets.
Despite having a win over Rainer Schüttler in the qualifying round for the 2007 Sony Ericsson Open (Miami Masters), Dorsch didn't manage to make it into the main draw.
