GMCSD was a member of the Gay and Lesbian Association of Choruses (GALA) and the San Diego Performing Arts League.

The Gay Men's Chorus of San Diego was a non-profit organization that operated under the umbrella of Finest City Performing Arts, Inc.

At the beginning of every season the group hosted an event called "Info Night" welcoming men who wished to sing with the chorus.

GMCSD was a self-identified "gay" chorus that was incorporated January 1993 in San Diego, and began rehearsing in the Great Hall of the Cathedral Church of Saint Paul on 5th Avenue, under the artistic direction of Gary Holt.

Each of the two 'legacy' choruses participated under their separate names in a joint holiday concert at San Diego's Balboa Theatre in December 2009.
