I have had the pleasure of working with Chris Hickman for over 25 years in the field of law enforcement. Chris is an excellent investigator who takes pride in his work and is very meticulous to make sure his results are correct and fair. I would recommend him to anyone looking for a trained, professional investigator.

I am an attorney and I hired Chris Hickman to investigate whether a client's employee had committed serious misconduct. It was difficult to determine the when, where, and how of it all and the situation was complicated by sensitivity and confidentiality. Chris did an excellent job of finding and interviewing people, finding and reviewing documents, and maintaining confidentiality all without offending anyone's sensitivities. He was professional, prompt, and fair. He made informed and well-reasoned conclusions and recommendations. I would not hesitate to hire Chris again.

HSI Special Agents, assigned to my office, worked with Chris Hickman for over ten years on numerous complex, multifaceted criminal investigations. I found him to be professional, dedicated, and diligent in his work. He is, without a doubt, one of the few “natural born” investigators I have ever had the pleasure to work with.

I have known Chris Hickman for over 35 years. My first experience with Mr. Hickman was as a defense lawyer and I found him to be an excellent officer and always well prepared. When he left the Great Falls Police Department in 2014 he had achieved the rank of Sergeant. He had served as the Commander of the Russell Country Drug Task Force. Since he left the department, I have utilized Mr. Hickman as a private investigator. He is very thorough and provides detailed reports that can be relied upon. I would highly recommend Mr. Hickman as a private investigator.
