The Lesbian and Gay Psychotherapy Association of Southern California (LAGPA) was established in 1992 as an organization of mental health professionals interested in gay and lesbian clients.

LAGPA members are actively involved in expanding the role of psychologists, psychiatrists, social workers, and marriage, family, and child counselors who serve the greater gay community of Southern California. 

While LAGPA is oriented toward mental health professionals, individuals desiring to join LAGPA are not required to be licensed.

LAGPA's purpose is to facilitate social and professional networking for mental health professionals in the greater Los Angeles area. LAGPA seeks to join such individuals together for academic and social events, to develop educational community outreach activities, to foster and promote a positive gay & lesbian identity, and to serve as role models for all members of the gay, lesbian & bisexual community.

Members of LAGPA are committed to the process of developing the finest psychological skills for working with clients confronted with the complexity of personal issues related to being homosexual in a homophobic world.
