Gay, Lesbian and Straight Education Network

GLSEN, the Gay, Lesbian, & Straight Education Network, is an organization founded in 1990 in the United States that seeks to end discrimination, harassment, and bullying based on sexual orientation, gender identity and gender expression in K-12 schools. GLSEN is headquartered in New York City, but has one office in Washington, D.C. to house the policy department. GLSEN focuses its efforts on the support and opportunities provided by the four pillars of safety, respect, health, and leadership. Through programs, research, policy, training, and resource development work, GLSEN has built a network of over 13,000 educators across the country.
