What to Expect from a Private Investigator in San diego

The workings of a detective agency are often shrouded in mystery and distorted by over the top depictions in television and film.  Your confidence and peace of mind are our first priority at Tristar, so we make the process transparent and easy to comprehend.

Here’s what we will do:

  • Consult with you to determine what your needs are
  • Together we will develop a strategy obtain the results you want
  • Discuss the costs and map out a plan that will minimize your costs
  • 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 consistently 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 association with a private investigator is something that must be kept confidential.  We will create a game plan that insures this.  For instance if you can take phone calls, the first thing we will say is “are you free to talk?” If you can’t talk at the time, you can say “wrong number.”  Texting and email are other alternative ways in which we can communicate.  With a total area of over 4,000 square miles, San Diego County poses communications and surveillance challenges that only the best equipped detectives can solve.
