Fantastic experience: Highly recommend! Duane with Cornerstone Investigative Services was able to track down our family’s 1968 Camaro which we were forced to sell during the ‘08 Recession. He found the current owners, who were just thinking about selling it when Duane told them we would like to buy it. Thank you Duane!

Fantastic experience: Duane with Cornerstone Investigative Services went above and beyond to complete an on-site interview that helped move my case along. I really appreciate the work done and the professional report that was generated. Would highly recommend and work with Duane again.
We're always grateful for the opportunity to work with solid companies and good people. Thank you for entrusting us with your case follow-up. We're looking forward to the next opportunity to work together.
Positive experience: Can't say my experience with cornerstone investigative was that helpful. Duane seemed unfocused and disinterested. I'm not sure if there was enough money in my story for him to be interested. I was surprised he didn't ask that many questions. I don't think he took me seriously. And he treated me very casually.
Jennifer, thank you for taking the time to provide a review. I must admit it took me by surprise since I left your residence with a different impression of our consultation. Nevertheless, I appreciated the invitation and opportunity to review your current home security situation. Meeting you in your environment was necessary to provide insight and offer some cost-effective home security improvements. Customer and client satisfaction have always been paramount to us. Our goal will always be to give our best professional effort in accomplishing the objectives of our clients, to leave them in better positions than when they found us. Even though you are not a client, it was equally important for me to recommend appropriate options for your situation. We will never try to upsell anyone without reason and the suggestions I offered were solutions I felt would address your current needs without the expense of hiring an investigator. Escalating security measures later is always an option.
