Wisconsin Investigation Services

This web page lists investigation services and private investigators in Wisconsin. Before visiting any of these Wisconsin investigation services and private investigators, be sure to verify their address, hours of operation, and appointment policies (if applicable). An investigation service provider may have ceased operations or moved to a different location, and business hours can sometimes be irregular, especially on and around holidays. So a quick phone call can often save you time and aggravation.
