Her calling cards in past seasons have been the Italian heroines Mimi and Musetta in LA BOHÈME, Violetta in LA TRAVIATA, Liu in TURANDOT, Donna Elvira in DON GIOVANNI, along with the French charmer Micaela in CARMEN.
Under the guidance of New York voice teacher, Bill Schuman, she is exploring the Prima Donna roles of Manon Lescaut, Madame Butterfly, and Tosca.
In Europe, the role of Mimi has served as her debut vehicle at the Marseille Opera, Nice Opera, Toulouse Opera, and Zurich Opera. She sang Musetta in the 100th Anniversary new production of LA BOHÈME at the Puccini Festival at Torre del Lago. Violetta was her debut at Saint Etienne Opera, and at Bern Opera, Switzerland, and Micaela was her debut in Sweden opposite the Don Jose of tenor Gosta Winbergh. In the U.S.A. she sang Musetta for her debut at San Diego Opera, Donna Elvira at the Philadelphia Opera, and the Spoleto Festival, Liu for the Colorado Opera Festival, and Mimi several times under the baton of conductor Anton Copola. It was for her exceptionally poignant portrayal of Mimi in LA BOHEME that she was invited to serve as the vehicle to open the newly formed Phoenix Metropolitan Opera in Arizona.
Rosemary made her professional debut with the Lyon Opera, France, while still a student at the Juilliard School, where she was hailed by the French press as 'an explosion at the opera that sets the stage on fire' as she appeared in a Mozart cycle as Susanna in MARRIAGE OF FIGARO, Despina in COSI FAN TUTTE, Zerlina in DON GIOVANNI, Papagena in THE MAGIC FLUTE, and Servilia in LA CLEMENZA DI TITO.
