Criminal Defense Investigations in the Bay Area

Independent, bilingual defense investigations for attorneys and the people they represent — from arraignment through trial. I find the facts, reach the witnesses others can’t, and document everything to hold up in court.

Oakland Roots, Bay Area Service

“My role isn’t to judge. My role is to find facts.”

Criminal defense is personal to me. Growing up in Oakland, I saw how quickly assumptions can shape someone’s future. I believe every person deserves a fair investigation and a real chance to have their story fully heard — and I combine lived experience with professional training to make that happen.

What Makes Me Different

  • Most investigators see a case file — I see a person.
  • I ask the questions that matter, because I’ve lived around similar environments.
  • I focus on people, context, relationships, and credibility — not just paperwork.
  • I know how to talk with people from every walk of life and earn trust that witnesses don’t give easily.
  • I understand Oakland, Bay Area culture, family dynamics, and community realities.
