John Zaffis (born 1955) is a paranormal researcher born and based in Connecticut, He runs the Paranormal and Demonology Research Society of New England, which he founded in 1998.
Zaffis has over thirty years of experience as a paranormal investigator.
Zaffis admits that he was initially very skeptical of the existence of ghosts, until one Wednesday evening when he was sixteen and saw a transparent apparition at the foot of his bed shaking its head back and forth. When he told his mother of the incident, Zaffis learned that his grandfather, when he was alive, always shook his head when he was upset about something. In the next few days, Zaffis’ grandmother, who lived with him, died. This incident peaked his interest in the paranormal and set him about talking to authorities in the subject and reading about the paranormal.
Zaffis spent his first years studying under his uncle and aunt Ed and Lorraine Warren, both demonologists.What he learned from his aunt and uncle exceeded his original interests in ghosts and haunted houses. Zaffis became interested in demonology at a young age, which led into his involvement with cases of spirit possession and exorcism and working with prominent exorcists in that field. He has studied the work of Roman Catholic priests, monks, Buddhists, rabbis, and Protestant ministers. Zaffis has also taken part in and assisted with the work of well-known exorcists like Bishop Robert McKenna, Malachi Martin, and Reverend Jun.
