The International Museum of Spiritual Investigations (IMSI) is a 501c3 Non-Profit that was devised in August 2009 to facilitate and show the general public what the spiritual investigations community does behind the scenes.


Founded by Jonathan Williams and supported by his Cousin Chris Williams, Christina Williams, and wife Brandy Williams, IMSI has a full outlook on what to achieve within the museum to make the experience an all in one visit.

Jonathan & Chris Williams currently have been investigating full time as a spiritual investigator since 1997 and has lead teams to investigate such locations as East State Penitentiary in Philadelphia, PA or Mount Osorie in Osorizan, Japan.


Since the doors opened in March of 2010, IMSI has catered to several hundred patrons in a workshop / educational capacity, and a few thousand in an exhibition capacity.

IMSI also secured its 501c3 Non-Profit Status on August 27, 2010 & is able to secure donations with no minimal or maximum cap.
