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.

I tried several other investigators to find a missing loved one -- and Mark was the only one who could help me. He is kind and smart. He is like Christopher Foyle. I am so glad I found him. Five stars for sure. Thank you!
