For seven years I’ve worked across Mexico on the questions that rarely have easy answers. Is this partner real? Where did the money go? Is this person who they claim to be?
I answer them the slow way, with lawful records, field checks, open sources, and interviews, then I write the answer so it holds up in a courtroom, a boardroom, or a claim file. I don’t guess, and I don’t promise outcomes I can’t support.

Away from the desk
Endurance keeps the method honest. The discipline a marathon build or a long trail run demands is the one a careful investigation needs.
