The Mira Costa Grammy® Award Winning Choirs provide students with an extraordinary opportunity to grow as musicians, engage with high-level musical literature, and experience the unique and profound social and emotional benefits of performing as a true ensemble of singers.
The Choirs have been recognised with distinct honours and many wonderful opportunities, including performing at the American Choral Directors Association National Conference in Salt Lake City and the California Choral Directors Association State Conference in San Jose. The choirs have also performed at locations and cathedrals around the world, including Carnegie Hall in New York, San Francisco, London, Paris, Germany, Strasbourg and Amsterdam.

Donations go directly to the program — coaching, equipment and season costs.
