Confidentiality: We know that often your contact with a private investigator is something that others must not know about. We will create a game plan that insures this. For instance if you tell us you can receive phone calls, but you can’t speak privately at the time we call, we will tell you to say “wrong number” or “I’m not interested.” Texting and email are other alternative ways in which we can communicate with you. With a total area of over 160,000 square miles, investigations in California pose communications and surveillance challenges that only the best equipped detectives can solve.
