AIDS Healthcare Foundation

AIDS Healthcare Foundation (AHF) is a Los Angeles-based 501(c)(3) nonprofit organization that provides HIV/AIDS prevention, treatment, and advocacy services, in addition to humanitarian aid. As of 2025, AHF operates about 400 clinics, 69 outpatient healthcare centers, 62 pharmacies, and 22 Out of the Closet thrift stores across 16 U.S. states, Washington, D.C., Puerto Rico, and 49 countries, with over 5,000 employees, and provides care to more than 2.5 million patients. The organization's aim is to end the AIDS epidemic by ensuring access to quality healthcare, including HIV and STD testing, prescription of medications like Pre-exposure Prophylaxis (PrEP), and referrals to specialty pharmacies. AHF is a participant in and supporter of the 340B Drug Pricing Program, and the largest provider of PrEP in the United States, though its founder Michael Weinstein has received criticism for his initial opposition to the drug in the early 2010s. AHF operates the Out of the Closet thrift store chain to help fund its services.
