In the aftermath of Ariel's death, and determined to save her son Jake, as well as to give hope to other HIV-positive children, Glaser co-founded the Pediatric AIDS Foundation in 1988 with friends Susan DeLaurentis and Susie Zeegen. Their work raised public awareness about HIV infection in children, and spurred funding for the development of pediatric AIDS drugs as well as research into mother-to-child transmission of HIV. In 1991, Glaser published an autobiography about her family's ordeal. The book was entitled "In the Absence of Angels", and it was co-written with author Laura Palmer.
