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 District of Arizona and the Central District of California, handling cases from Phoenix to Los Angeles.
"The worst thing you can do when you suspect you're under federal investigation is wait. The second worst thing is hire the wrong lawyer. I know how these cases are built because I used to build them."
