P.E.D.R.O is the joint creation of team members Jennifer and Lisa, who founded the organization in 2002. The founders determined a need for such a body when their twin interests in paranormal phenomena and writing led them to a first tentative investigation of a historic site in Neosho County, Kansas. That experience convinced them that their study of paranormal phenomena need not be subordinated to any single literary project (they were researching the Bender family of Kansas serial killers at the time) but should rather give shape to an enduring organization, the purpose of which is to investigate paranormal phenomena and document that research. The Paranormal Encounter Documentation Research Organization, or P.E.D.R.O, is the result.

Over the course of so many investigations, Jennifer and Lisa encountered not only spirits, of course, but also people, several of whom expressed an interest in joining the group and brought to it valuable experience and assets. In the Fall of 2004, P.E.D.R.O held its first formal organizational meeting and accepted two new team members, Janet and Joe. Both have become active participants in P.E.D.R.O investigations. At the same time the group arranged for the creation of this web site as a further means of documenting their research. 

In 2009 a fifth team member was fadded! The P.E.D.R.O. team welcomed a long-time friend and paranormal enthusiast, Dawanna!
