Padilla was raised in Red Bluff, California and briefly lived in Los Angeles and Orange Counties. During his youth, many of his summers were spent in Ketchikan, Alaska.
His experiences as an insurance claims adjuster involved him traveling throughout the U.S. for disaster duty. While handling liability claims, he found himself in court rooms and had a good understanding of the legal process. It's no surprise his reading influences were early Stephen King, Tom Clancy, and John Grisham.
Padilla's previous works include "Rule One Twenty," "Michaso (the Korean word for crazy)," and "Tunnels" (2018 American Book Fest finalist Thriller: General category). The sequel to Rule One Twenty is titled "Sentinel Event" (2019 American Fiction Awards finalist Thriller General category). He also wrote "Gamers" and "Harpazo." He is currently working on his seventh book with a working title of "G3: The Journey."
