LGBT liaison officers or Gay and Lesbian Liaison Officers (GLLOs) are individuals who work within organisations as a point of contact.
They build rapport and trust between an organisation and the communities they serve.
[1][2] LGBT liaison officers also raise issues within organisations that may impact LGBT communities and play a significant advocacy role when developing policies, programs, and services.
[3] LGBT Liaison Officers have been appointed since at least 1962, when San Francisco Police Department appointed Elliott Blackstone as the United States' first liaison officer to the "homophile community".
A pioneer of community policing, Blackstone worked within the police department to change policy and procedures directed against the LGBT community, such as entrapment of gay men in public restrooms.
