"I want to thank you and all for "tracking" me down in this remote location, and for your expeditious handling of my inheritance."

Respectfully, Bill Massengill

"I had hired an investigator to ascertain the dates of death and whereabouts of next of kin to Ruth Evans. After two months of diligent searching, he found nothing concrete… Within two days following our first conversation, I received a call indicating the possibility of success. It was indeed my long lost relative. I only wish I had found and used you sooner."

    Webster B. Baker Attorney at Law
  • As we discussed, six years ago,

    you did a fine job for me in a case about which I’ve spoken in classrooms to paralegals, and to lawyers at seminars. The family tree you provided covered 3 out of 4 of the courtroom’s walls. An amazing case. Not sure this assignment will rise to the level of that one, but nevertheless I am sure you are up to the task. I have been appointed by the Court as the Attorney ad Litem to find the missing heirs. Thank you very, very much for your willingness to help us in this case.

    Randy Michel Law Office of Randy Michel
