Criminal Defense Investigations — Backed by Experience, Strategy & Community Insight

Bilingual, Bay Area defense investigations for attorneys and the people they represent. I uncover the facts, find and interview the witnesses others can’t reach, and help build a defense that’s heard in full.

Criminal Defense Focus

Bilingual · English & Español

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.
