Working with Mark was one of the best decisions I’ve ever made. He handled my situation with genuine care and discretion. He never made me feel judged, he just wanted to help. Mark went above and beyond to uncover the answers I needed, and I’m deeply grateful for his hard work. If you need someone you can trust, Mark is the one.

I reached out to Mark about a human trafficking problem. He stuck with me for over six months to address my concerns and to find a missing loved one. He helped me and didn't give up. He was prepared to go to Capitol Hill to meet with our congressman and tried to engage non-profits and the FBI to help us. I am so glad I found him and am grateful. Five stars Excellent! Thank you!

Fortunately I was able to locate who I needed in time, but before that, Mark responded to me almost instantly and was as serious about the matter as I was. I respect his professionalism and his urge to help.

Mark was very open about the realistic approach to my request. He did what I had ask him to accomplish at a very reasonable fee.
