The Gay and Lesbian Medical Association (GLMA) is an international organization of 2,000 lesbian, gay, bisexual, and transgendered (LGBT) physicians, medical students, and their supporters in all 50 U.S. states and 12 countries. Founded in 1981, GLMA "works to combat homophobia within the medical profession and in society at large; to promote quality health care for LGBT and HIV-positive people; to foster a professional climate in which our diverse members can achieve their full potential; and to support members challenged by discrimination on the basis of sexual orientation." 
Gay and Lesbian Medical Association works to ensure equality in health care for lesbian, gay, bisexual and transgender (LGBT) individuals and health care professionals. GLMA achieves its goals by using medical expertise in professional education, public policy work, patient education and referrals, and the promotion of research.
