Mission: To serve people living with or at risk for HIV with dignity and respect.
Vision: In our community, people living with HIV receive quality care, and new infections are rare.

AOC began in 1986 in response to the HIV/AIDS epidemic among gay males as an all-volunteer organization in order to provide support to those dying from the disease. In just two years, the demand for services from AOC resulted in the hiring of its first two paid staff members and support quickly grew. Today, AOC has more than 30 staff members dedicated to providing 10 services aimed at preventing the spread of HIV, bringing those newly diagnosed into treatment, and improving the lives of those infected or affected by HIV.

AOC provides support services to more than 1,600 individuals and their families across all races, ethnicities, genders, ages, and sexual identities. AOC is currently the only non-profit organization that offers a continuum of support services to the HIV/AIDS community in Tarrant County and seven surrounding rural counties.

I have been a client for a few years now. The services hand helped me tremendously! The dental clinic was during this visit and Laurie/staff are fantastic! Thank you AOC for all you do for all of us!
