This concern led him to found the PWA Health Group with Michael Callen and Thomas Hannan in 1986. This non-profit organisation was the first and largest formally recognised AIDS buyers' club, which aimed to widen access to promising AIDS therapies not yet approved by the FDA; the PWA Health Group went on to become an important source of AIDS treatment education and advocacy. In 2000, PWA Health Group merged with Direct Aids Alternative Information Resources (DAAIR), but the combined organisation closed in 2003 and was superseded in July of the following year by the New York Buyers' Club.
