Following these 2 seasons she was chosen to sing THE TELEPHONE by Menotti in the Bell Pavilion at the World Expo in Vancouver, B.C.. In 1986 Donna was accepted as one of fifteen singers from around the world for the prestigious ZÜRICH OPERA STUDIO in Switzerland which was then made possible for her to attend through a generous grant from Canada Council and many generous donations of citizens in the Guelph area. This was followed by a contract at the Linz Opera House in Austria, where she sang over 35 roles as the leading lyrical coloratura for the following 10 years. These roles ranged from "Susanna" in THE MARRIAGE OF FIGARO; "Blonde" in THE ABDUCTION FROM THE SERAGLIO, Gretel in HANSEL AND GRETEL, Marie in DAUGHTER OF THE REGIMENT, "Oscar" in MASKED BALL etc. to the "Queen of the Night" in THE MAGIC FLUTE.

She has also sung many world premieres of contemporary composers in opera and concert. She was engaged by Pamela Rosenberg for the role of "Die Gefährtin" in INTOLLERANZA by Luigi Nono, which led to her appearance as the "Protagonist" in UN RE IN ASCOLTA by Luciano Berio, who attended performances in Geneva, Switzerland. Donna was then immediately engaged for another production of the Nono Opera in Saarbrücken, Germany for the 2004 season with stage designer Daniel Libeskind, the newly appointed architect for the World Trade Center in New York.

Donna has travelled extensively through China, Japan, Armenia, Greece, Germany, Holland, Belgium, England, Serbia, Kasachstan, Azerbaidchan and France as "Ambassador" for the City of Vienna's CULTURAL EXCHANGE DAYS representing the music of Johann Strauss and his contemporaries.

Donna Ellen gave her debut at the VIENNA STATE OPERA as "Helmwige" in Wagner's DIE WALKÜRE under the direction of Donald Runnicles and consequently sang the following season's series.

She then debuted successfully in 2004 at the VIENNA VOLKSOPERA as Donna Anna in DON GIOVANNI, the 1st lady in THE MAGIC FLUTE and this season in THE BARTERED BRIDE.
