Gasser was an Artistic Gymnastics World Cup silver medal winner on the uneven bars in Osijek in 2010.

After that she lived and trained in Sarnia, Ontario, but since she still had Austrian citizenship she continued to compete for Austria.

She made her comeback at the 2010 Austrian National Championships, where she won the all-around, the vault and the uneven bars.

At the 2011 World Championships in Tokyo, Gasser's results earned the highest ranked Austrian gymnast a place at the 2012 Olympic Test Event.

She was the highest ranked Austrian gymnast and competed at the Test Event where she achieved Olympic qualification.

This was a historic success for an Austrian gymnast, as Gasser was the first female Austrian gymnast to qualify for an Olympic Games since Henriette Parzer (Behrendt) qualified for the 1964 Tokyo Olympics.

At the 2012 Olympics, she was joined by another member of the Vorarlberg Gymnastics squad, Caroline Weber.
