Our Approach

Our Approach

The philosophy at Mantis is to treat all task assignments as a blank slate, with no preconceived or subjective notions.  We see investigation as an holistic endeavor; utilizing surveillance, in-depth background and deep social media digging to paint a realistic picture of the claimant's current capabilities and past activities. 

Our Story

Our Story

The Mantis agency was founded in 1977 by John Spray, and was a one man show for the first two years. Eventually, his recipe for successful investigation, combining surveillance with thorough background checks, increased business to an extent that additional staff was added. John takes great pride in the agency he founded and strives to ensure the Mantis product meets the highest industry standard.
