Former U.S. Federal Prosecutor. Before defending federal criminal cases, John Kirby prosecuted them. He understands how federal investigations are structured, how charging decisions are made, and where the prosecution's case is weakest.
With over 25 years in federal courtrooms, he brings a perspective most defense attorneys cannot offer: firsthand knowledge of how the other side thinks. He practices in the Southern District of California, Central District of California, and District of Arizona, handling cases from San Diego to Los Angeles to Phoenix.
