Jan Groenveld

Jan Groenveld (1945 – 22 October 2002) was an Australian Christian countercult activist. She was a member of the Latter-day Saints Church and the Jehovah's Witnesses. She spent fifteen years in these and other organisations before leaving them in 1975 and resolving to make more information about what she saw as cults available to the general public.

Anti-cult activities Groenveld first began providing information about groups she referred to as cults to the public and counselling affected individuals in 1979. whose purpose was to counsel former members of controversial groups and provide information about coercive religious sects.

Groenveld founded the Cult Awareness and Information Centre (CAIC) in 1990.

Groenveld was particularly active against the Jehovah's Witnesses, modern Satanism, and the occult, but she also combatted the influence of other groups – like Scientologists – in Australia.

Groenveld first met Steven Hassan in 1993, when she brought him to Brisbane, Australia, from the United States for a seminar. Hassan educated Groenveld as to the "serious potential for doubt and lack of veracity in satanic ritual abuse stories". Other Australian publications like The Courier-Mail, a Brisbane tabloid, and The Mercury, a tabloid in Hobart, titled her a "cult expert." She warned the publication about a cult called the Twelve Tribes Mission, believing them to possess militant tendencies. She warned that "There are people out there all over the place who would like to be another Jim Jones", referring to the Peoples Temple suicides.

Death Jan Groenveld died in October 2002, and was survived by her husband, 3 sons, 2 daughters and 2 foster daughters.
