Our guest, Dr. Richard Gallagher, is a well-known psychiatrist, author, and professor who has spent his career studying the intersection of psychology, spirituality, and the supernatural. One area of Dr. Gallagher's expertise that has garnered significant attention is his work with demonic possession and exorcism. He has evaluated and treated many individuals who claim to be possessed by evil entities and has served as a consultant on numerous high-profile cases of alleged possession. In this capacity as the consultant for Exorcists, Dr. Gallagher has undoubtedly seen more cases of possession – many quite disturbing – than any other physician in the world. He has also written extensively on the topic, including his recent book, "Demonic Foes: My Twenty-Five Years as a Psychiatrist Investigating Possessions, Diabolic Attacks, and the Paranormal."
