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