She has also been part of the continuo team for opera productions, major choral works, and the ensembles Concerto Baroque and Seattle Trumpet Consort. Sheila’s harpsichord training includes workshops (Pacific Music Work’s Accademia D’Amore, Cornish College’s Summer Baroque) and private study with Jillon Stoppels Dupree and Carole Terry. 

From a Tacoma News Tribune review of Tacoma Opera's 2008 production of The Barber of Seville: "Congratulations to harpsichordist Sheila Bristow, who supported this opera's lengthy recitative with nimbleness, creativity, and verve".
