Below listed are a number of groups of paranormal researchers who are of reputable status. If they are in red I have worked with them and have a good reputation with them. If they are in Green, I have never worked with them.
*Eastern Paranormal of Wilmington North Carolina- www.easternparanormal.com
Operated by Gabreael from Wilmington NC. Gabreael is the closest person to a demonologist in our area that I would recommend.
*New England Society for Psychic Research-
www.thewarrens.net
The famous group of the late Ed and Lorraine Warren of Connecticut. I am an associate member of NESPR and consult with Lorraine about once or twice per year on cases I get. A great group and highly experienced.
*Phantasm Psychic Research-www.phantasmpsiresearch.com
Operated and run by Mr. David Considine and Ms. Barbie Hied. Dave is a great investigator and Barbie is a great medium. They have helped me on several cases from New England.
*Vanderworker Todd Paranormal Research-
www.snuzz420.tripod.com
Run by Sarah Vanderworker from Nebraska, I have worked with several people referred to me through this group and I will tell you they are a first rate group open mined to different possibilities.
Rochester Paranormal Society-
http://supernaturalparanormal.com
Director J. Burkhart is one of the most talented demonologists I have had the opportunity to work with. I highly suggest anyone in the western New York area use him.
Perry Hall Paranormal Research Society-
www.phprs.org
BJ is the close friend of Mr. Bill Bean a close personal friend of mine and I am sure if you need help and are in the Baltimore area you can call on him.
*John Zaffis-
www.johnzaffis.com
John has a reputation that definitely proceeds him, but I have never had the pleasure of working with him.
*Southern Maryland Paranormal Research-
www.somdparanormal.com
I have not had much experience with these folks, but a good friend of mine recently became a member with them and I have heard good things. Although I normally do not sanction anyone who are members of the TAPS family, I will grant an exception for them.
