People are referred to Compeer only through mental health provider agencies or private therapists. Compeer same gender friendships are an adjunct to therapy and other community support services.

A Compeer volunteer is a man or woman who shares friendship with someone socially isolated by mental illness and economically disadvantaged. He or she is a sensitive person who understands and accepts someone who may feel misunderstood or rejected.

In the Compeer program, both the volunteer and friend become 'compeers' or co-equal partners in this relationship. They spend at least four hours a month together, seeking to have weekly contact whenever possible.
