After using Golden State Detectives, I can confidently say that Peter and Kimberly were very knowledgeable and helpful. I highly recommend this company to anyone.
I was suspicious that my husband was stepping out on me. My gut was telling me but I needed proof. I found this firm online and it was the best decision. The response time was quick and once hired they got straight to work. Let’s say I got all my money’s worth. I recommend this firm for any investigation needs. Well worth every dollar.
My attorney hired this company to do some surveillance on my behalf and they worked out very well. They are extremely professional and get the job done efficiently in a timely manner. I would use them again and highly recommended them to my family and friends.
I’m very disappointed. I paid a significant amount to Golden State Detectives-Wiley who promised results with the info I provided, but I got nothing useful. Now they’ve stopped responding, even after receiving my messages—that’s really unacceptable. It feels like a total waste of time and money. This isn’t how professional service should work—shouldn’t at least part of the fee be refunded?
Golden State Detectives exceeded my expectations in every way. When other private investigation companies in California wouldn’t give me the time of day, Peter and his team not only listened but immediately took action. From the moment I reached out, they hit the ground running, leaving no stone unturned. Their professionalism, responsiveness, and discretion were impressive, and they kept me informed with clear, thorough updates throughout the investigation. If you're looking for a reliable, trustworthy private investigator in California, I highly recommend Golden State Detectives. Their top-notch service and expertise is legendary.
