SPI - Arizona's Leading Paranormal Investigators!

Sonoran Paranormal Investigations (SPI) is a paranormal investigation group located in and serving the state of Arizona. We have members from Flagstaff to Tucson and we are able to meet the needs of families and businesses throughout the entire state.

In 2007, we were proud to become TAPS Family Members. You may be aware of TAPS (The Atlantic Paranormal Society) and TAPS Family from the Sci-Fi channel series Ghost Hunters.

Becoming involved with the TAPS Family not only ensures that we are doing the right thing - but it keeps us doing the right thing. The TAPS Family affiliation provides SPI and our clientele with access to some of the best and brightest in the field and ensures that we have access to the latest information and knowledge of the latest technology available.

Our unique approach to professional investigation has set SPI apart among investigative groups. We have been called in by homeowners and business owners but also by government agencies including historic sites, local and state government (including police), and the United States Army.
