The Crescent will next year celebrate its 30th anniversary, having been founded on the first World Aids Day (1st December 1988).  This drop-in centre in St Albans provides a wide range of advice, information, services and support by and for those living with HIV as well as their families and friends.  It also provides HIV testing and guidance for those at risk.  All its services are confidential.  In this interview, the man who runs The Crescent (Iain Murtagh) tells Rob Pearman about its history (and the history of HIV/AIDS) and then describes the services offered by professionals and volunteers.  He also explains how The Crescent has managed to survive despite its loss of major funding by NHS and Hertfordshire County Council as a result of budget cut-backs.
