Confidential and efficient work. Amazing. Couldn't recommend Arrowhead more highly…read more I had been having issues with a custody case and my attorney recommended that I hire a private investigator. My friend had met a woman named Kelsey who gave him her card. He said that she was extremely intelligent so I gave her a call. Since I am currently out of state, I was worried about communication. However, Kelsey quickly got in touch with me. We had an initial video call that lasted about an hour. She was creative with how to get the information I needed. I paid a retainer to get Arrowhead Investigations started on an intensive background investigation and two days of surveillance. One night, I got the scoop on some activities that I thought could be useful for the investigation. I called Kelsey at about 1am and she was filming within the hour. It was reassuring to know that I had someone on my side like that. This investigation took about two weeks. Any time I had a question, Kelsey was easy to reach. At the end of this, I received a substantial report and a DVD with footage and photos. The investigation found a few pieces of unexpected information that gave me an extra edge. For my first experience with a private investigator, Arrowhead Investigations was awesome. My attorney was also impressed with the work.

On February 15, 2025 I went online to look up private detectives in the Denver, Colorado area. Our…read morefamily member was missing and I needed somebody good and strong. I chose Alexandra because she had five stars. I also chose her because she was a woman and I thought if she was a mother as well she might be more effective. It's probably the best decision I've ever made in my life. Alexandra worked day and night to find my family member. There were days we were both frustrated and she always gave advice to me like a real friend would. She truly cared about my family member as well as my family. We are very private and there were times I needed to talk about things and she was always there for me. The first time I spoke with her I knew we made the right choice. Unfortunately, my family member had fallen in Black Canyon while hiking. It was extremely important for my family member's mother to have a timeline. Alexandra sent her team out to Montrose and she created a timeline down to the minute. I have no idea how she did it but she did and she was spot on. There were days I thought the park Rangers would stop looking and she reassured me that would not ever happen. She even went to the extent of calling companies to search just in case they stopped looking. They didn't stop. They found him and brought him home to us. Alexandra was dealing with multiple jurisdictions. She was also dealing with the press who had many questions. There were days I had no idea how she was doing what she was doing but she did it. She did it with love, kindness, grace and support for us. If you hire Alexandra you will be getting the best private detective there is. We will always consider Alexandra not just the best private detective but our family now too.
