I will be hiring Cocidius again in the near future. I found them to be extremely knowledgeable and straight forward. I was very satisfied with the professionalism and the time Eric took to make me feel important. He did not charge me because the time frame he gave was a problem due to staff issues. Thank you Eric and Jason!! You changed my opinion of private investigators.

⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️ Is there a ten star option?🌟 because that's what he is, he is above and beyond what you expect. What can I say here except that my expectations were blown right out of the water he was that good. He came out to meet me within an hour of me calling and consulting over the phone. During our in person talk we discussed the situation and he listen to me for about an hour possibly longer in relation to everything that was going on. he would not even discuss price and he had told me that he wanted to make sure that he could help me before he charges anything. Someone that honest that quality driven is RARE,🌹extremely rare. By the time I was done filling him in on everything he stated that he thought at this point it would be better to go and alternate route because he felt that at this point it would be more price effective for my particular situation to focus on the free things I can do rather than jumping into paying for services but he said that if I don't feel comfortable with that he can absolutely move forward and start right away. I was wanting to cry I was so happy talking to someone who actually cared about my situation and was giving me advice based on my best interest I can't tell you how much that meant to me. If that wasn't already amazing which it is he then stated that there is a certain course of actions that he thought would be effective he gave me a detailed step-by-step of what I should do and he also offered to help me facilitate that procedure that he was recommending. I left the meeting feeling refreshed and feeling that I was able to see it from a more level view as it wasn't being distorted from my emotional status. Honestly he could also make a great psychiatrist LOL!! He is very low pressure and makes you feel at a ease during a time you probably don't feel so well and honestly that was very significant for me. In terms of his background he has a very impressive background in law enforcement! Also the rate he quoted me was extremely fair, I honestly think he should charge more for his services. I will not hesitate to call him again when I need PI help, thank you again, you don't know how much it meant to me! I finally felt like I had control back again I don't know what I would have done without his help 😊Sincerely Lala

I needed a process server and I am glad I went with Justin. The address my defendant gave to the police was incorrect and he tracked her down to her real address. Thanks to him, I was able to win my suit and recover all that was owed to me!

Mr. Jason Earls did an outstanding job of providing security at our HOA meeting on March 9, 2014. He was very professional; prompts; courteous; dressed well; perceptive; a great listener and obviously has had much experience in dealing with difficult personalities. He assured our physical safety and told us it was his number one priority. The meeting last an hour and a half and his full attention was present the entire time. Plus, his feedback on his observations of the meeting were invaluable to us. We would hire him in a heartbeat if need be. Thank you.

I originally hired one security guard to escort my mom to retrieve her belongings since there were no civil standby available, but he offered to bring an extra guard at NO EXTRA CHARGE just to be more safe. Dave and Trent were very nice, professional, helpful, know what they were doing, fast, and they even gave me details and answered any questions promptly. The communication was very effective. Will definitely use their services again! The rate was very reasonable. Hire them and you won't be disappointed!
