What to Expect from A Private Investigator

Here’s what we will do:
  • Speak with you at length to determine what your needs are
  • Together we will develop a game plan to obtain the results you want
  • Discuss the costs and develop a plan that will minimize your budget
  • Tell you the time frame for which you can expect your  investigation to be conducted
  • Assign an experienced agent to conduct the investigation
  • Communicate with you regularly during the process of the investigation
  • Deliver to you the results in the form of a detailed report and video when appropriate
  • Follow up with you to be sure you are satisfied with the service provided
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.
