Nov 15, 2016 Report
For many years, and in a number of different situations, I have contacted Ryan Ross for needed information. The results were always prompt and complete and accurate. Ryan responded immediately, and sometimes was able to obtain the requested information despite having less than complete factual information from which to proceed, I would recommend him and his services without question.

Ross has been my go-to investigator for a good 10 years or so. When a process server cannot locate someone, Ross seems to be able to find them and get them served, no problem. I once had a case where a number of undocumented immigrants were the defendants, Ross was somehow able to locate them. His attention to detail and turn around time are unmatched. He's extremely efficient with my client's resources as well. I've been recommending Ross for years.

I was nervous about hiring a private investigator. My imagination took me to the seedy and undignified but the experience with Ross Investigators was completely professional. My attorneys, with Holland & Hart, commented on Ross Investigators' thorough work, documentation and clear presentation of facts, relevant in a court of law.

Ryan Ross together with the entire team at Ross Investigators are truly top notch. The firm has proven to me time and time again that they will do whatever it takes to uncover the truth. Thorough, responsive, and dedicated professionals. You get what you pay for in this business, and they aren't the cheapest in town, but I have never regretted writing a check for a job well done.
