Sørensen began learning to skate in 1996 at his father's instigation. He competed internationally with Anne Thomsen beginning in 2003. They placed twenty-fourth at the
2006 World Junior Championships. In 2007, Sørensen teamed up with Czech skater Barbora Heroldová to compete for Denmark. They competed one season together, placing twenty-first at the
2008 World Junior Championships. In 2009, Sørensen began competing with Canadian skater Katelyn Good for Denmark. In their first season together, they won the Danish senior national title, placed seventeenth at
2010 World Junior Championships, twenty-first at the
2010 European Championships, and twenty-fourth at the
2010 World Championships. The following season, they decided to move from training in the United States under
Mathew Gates to Montreal to be near Good's mother. On Gates' recommendation, they began training under
Marie-France Dubreuil and
Patrice Lauzon, whose just-opened ice dance academy had only four teams at the time. Shortly after the move, Good's mother died. Sørensen and Good placed twenty-ninth at the
2011 World Championships in their final performance together, as Good chose to retire due to injury. In 2012, Sørensen began skating with Canadian skater
Vanessa Crone, but she decided not to compete with him. == Partnership with Fournier Beaudry ==
