My attorney had a field day!
Going through with my divorce was a walk in the park. The evidence of unbecoming behavior that I accumulated courtesy of Corinthian Group’s surveillance investigators was enough to make my case in court and my attorney had a field day. Thanks guys for helping save my life.

Within weeks our theft issues had disappeared!
Our company was incurring loss due to employee theft and Claude was hired to help detect how the loss was occurring and implement a solution. Within weeks our theft issues had disappeared and we have suffered no further loss. Claude was professional, diligent and offered a variety of solutions to our company while maintaining a high degree of integrity. I would recommend his services to others with similar problems.”
