John Zaffis has over thirty years of experience studying and investigating the paranormal. He has had the opportunity to work for, and with, his aunt and uncle, Ed and Lorraine Warren. John has assisted and worked with well-known exorcists who include Bishop Robert McKenna, Malachi Martin and the Rev Jun. Through hands-on work with other investigators and clergy, he has obtained a great deal of knowledge and understanding of the paranormal and is considered one of the foremost authorities in the field today.
He has also worked extensively with both spiritualists and psychics concerning how their knowledge is used for channeling, reincarnation, or the calling of the spirits for information. John has been featured in Discovery Channel documentaries and has appeared on Unsolved Mysteries, Fox News Live, and many other print and news media events. John's first book, Shadows of the Dark, co-written with Brian McIntyre, was recently released and he is currently working on multiple follow-up books.
