The AIA Story

Advocate Investigative Agency was established in Southern California and has since proudly expanded nationwide. We’ve built a strong and dedicated team that work to provide the highest level of investigations and evidence that our clients can actually use in court. Our policies and procedures are regulated by the CA PI Act and BSIS. It’s vital that we only utilize licensed and insured investigators in every city and state where we conduct investigations.

In a fraudulent world, you would think all investigators who claim to combat fraud are ethical, but that’s not the case. At AIA we take pride in always being truthful and transparent with our clients and provide ethical, unbiased investigations and usable results. We value our clients, our team, and our investigators, and have built a culture that revolves around honesty, integrity, and personalized customer service.
