When using a private investigator, one would hope your identity (the client) would be private also. This was not the case for me when using Jacob's services. I only hired him to do a "skip trace" ($200) to obtain the contact information of the landlords/homeowners of a property. It would never occur to me in 1000 years a PI would MAKE PHONE CONTACT WITH and REVEAL the identity of their client (me) to the subjects of an investigation, all in the name of "transparency," said Jacob casually and robotically. In fact, by doing a quick Google search, one can discover it is industry standard for a PI to maintain their client's anonymity and confidentiality up until a certain point i.e. legal proceedings, etc. He has compromised me, telling the subjects of investigation that I (the client) would be reaching out to them. I wanted to make contact with the subjects on my own, at my own leisure - if at all! It was my choice and he took that away from me by making assumptions. I am not sure if it is naiveté, stupidity, or sociopathy that would make Jacob think doing this would be OK. I think a reasonable person would find this bizarre and unprofessional. I am extremely angry. Thanks, Jacob for potentially putting my family and me at risk.

Jacob was very professional and prompt. He responded to all of my contacts expeditiously. He was able to serve the opposing party with ease and the prices were very reasonable. If we had a need for a serve in this area again, we would definitely use him.
