Rosemary Thomson is equally at home conducting orchestral, choral, contemporary and operatic repertoire. Rosemary spent four seasons as Assistant Conductor to Richard Bradshaw at the Canadian Opera Company and also trained in opera at the Banff Centre for the Arts. She has guest conducted for ​Opera Garden in Scotland, Calgary Opera, Highlands Opera, Vancouver Opera, the Canadian Opera Company, and recently for Tapestry Opera in Toronto, where she was nominated for a prestigious Dora award as Music Director for the world premiere of Shanawdithit, composed by Dean Burry with libretto by Yvette Nolan. ​

Inspired by training she received from Hans Graf, Boris Brott and Bramwell Tovey, Thomson enjoys a reputation for working with emerging artists in both festival and university programs, most recently with Opera Kelowna’s own Valley Opera Summer Intensive. As a regular conductor and faculty member of the established Opera Nuova summer training program​ in Edmonton she has helped to train over five hundred young Canadian singers.
