MISSION GLMA is a national organization committed to ensuring health equity for lesbian, gay, bisexual, transgender, queer (LGBTQ) and all sexual and gender minority (SGM) individuals, and equality for LGBTQ/SGM health professionals in their work and learning environments. To achieve this mission, GLMA utilizes the scientific expertise of its diverse multidisciplinary membership to inform and drive advocacy, education, and research. HISTORY GLMA: Health Professionals Advancing LGBTQ Equality (previously known as the Gay & Lesbian Medical Association) is the world's largest and oldest association of lesbian, gay, bisexual, transgender and queer (LGBTQ) healthcare professionals and allies. GLMA was founded in 1981, as the American Association of Physicians for Human Rights, with the mission of ensuring equality in healthcare for LGBTQ individuals and healthcare professionals. Today, there is still considerable ignorance about LGBTQ health issues, with many assuming that LGBTQ health involves only HIV/AIDS. In fact, the full scope of the LGBTQ health agenda includes breast and cervical cancer, hepatitis, mental health, substance abuse, tobacco use, depression, access to care for transgender persons and other concerns. For nearly four decades, GLMA has tackled many initiatives and projects. Early on, GLMA focused on HIV/AIDS and the issues faced by physicians coming out at work. As the climate and culture have changed, GLMA has become a leader in public policy advocacy related to LGBTQ health.
