The Four Pillars of Our Investigative Services


We move as quickly as possible without compromising the quality and integrity of the investigation.


We only target opportunities that we feel have a high probability of producing a result. This discipline produces better outcomes and saves the client money.


We never forget that our work is connected to a human being. Our responsibility is to understand our client and problem we are trying to help them solve.


We insist on transparency and openness. We only accept clients who we feel we can help and who have an understanding of the realities of producing the result they desire.
