John Zaffis is one of the best-known and most popular authorities in the paranormal. His career of more than 40 years began with working with his uncle and aunt, Ed and Lorraine Warren, noted investigators and demonologists. John was drawn into paranormal investigation and demonology, and gained firsthand experience in cases of hauntings, possession, and exorcism. He has worked with prominent exorcists in Roman Catholic, Protestant, Jewish, and Buddhist faiths, among them Bishop Robert McKenna, Father Malachi Martin, and the Reverend Jun. John's research has taken him throughout the United States, Canada, England, and Scotland. Over the years he has handled thousands of cases involving ghosts, poltergeists, demonic and diabolical entities, and haunted objects. He has also worked extensively with mediums and psychics concerning the afterlife, spirit communication, near-death experiences, and past-life recall. John has been featured in numerous documentaries, television shows, and films, among them the Discovery Channel's A Haunting in Connecticut and Little Lost Souls; NBC's Unsolved Mysteries, Fox News Live; Piers Morgan Tonight, Ghost Hunters, and Ghost Adventures. For three seasons, he starred in his own paranormal reality show about haunted objects, Haunted Collector, on SyFy. He was a producer of the show in its last season. The series was picked up for reprise by Destinationa America. John Zaffis: The World Within, a documentary on his life and work, was released in 2010 by Scared! Productions. John is featured in The Encyclopedia of Demons and Demonology by Rosemary Ellen Guiley, and in Graveyards and In A Dark Place, by Ed and Lorraine Warren and various co-authors. John's first book, his autobiographical Shadows of the Dark, co-written with Brian McIntyre, was released in 2004. He is co-author, with Rosemary Ellen Guiley, of Haunted by the Things You Love, about haunted objects in his case files. In addition, John runs the Paranormal Research Society of New England, an investigation group he founded in 1998. He makes numerous appearances on radio and is always in demand as a presenter at paranormal conferences and at colleges and universities. Over the years, John has collected hundreds of haunted items in his casework. In 2004, he created the John Zaffis Museum of the Paranormal for the collection. John scripted and starred in a documentary film Museum of the Paranormal, released in 2010 by New Gravity Media, which gives a tour of the museum and highlights some of the haunted objects.
