At the 1989 and 1990 European Curling Championships she played lead for skip Andrea Schöpp, and won a gold medal at the 1989 event.

Due to a disagreement with the German Curling Association, Schöpp was replaced at skip with Natalie Nessler, her long-time third.

Team Germany greatly improved their performance compared to the 1998 Games, finishing 5th with a record of 5-5, missing the playoffs by one spot.

Schwaller reappeared on the international curling stage at the 2010 World Championships, this time representing her new country of Switzerland.

[11] Schwaller's brother-in-law, Christof, is also an elite curler and played third for his brother Andreas at the 2002 Olympics.
