Virtually unknown in the U.S. before her American concert debut at the Weill Recital Hall at Carnegie Hall in 2008, the Swiss-born actress and singer was embraced in her first appearance at the Mabel Mercer Cabaret Convention in 2010. She recently starred in Gypsy at the Lyric Stage in Irving, TX.

Mathys starred as Norma Desmond in the German premiere production of Sunset Boulevard (directed by Trevor Nunn), and the German premieres of Sweeney Todd and The Rocky Horror Show. She portrayed Johanna Spyri in the Swiss world premiere and German premiere of Heidi, a musical based on Spyri's world-famous novel. She starred as Maria Callas in Master Class, as Rizzo in Grease and in the title role of Piaf, for which she earned a Prix Walo as Outstanding Actress. She has also appeared as Sally Bowles in various German, Austrian and Swiss productions of Cabaret.
