Born and raised in the San Joaquin Valley, I graduated from California State University of Fresno and the University of the Pacific McGeorge School of Law. After law school, I returned home to practice law and began my career at the Fresno County Public Defender’s Office in order to gain valuable trial experience. When I left the Public Defender’s Office and decided to open my own practice, I was on the “Major Crimes Team” which consisted of attorneys that handled the most difficult criminal cases like homicides, Three Strikes cases, cases with high prison exposures, cases involving complex legal issues, cases with a voluminous amount of discovery and cases receiving media attention.
I am recognized by the California State Bar as a Certified Legal Specialist in the area of Criminal Law and certified to handle death penalty cases.
In my spare time, I enjoy spending time with my family and working on the family farm growing almonds, pistachios, cherries, and raisin grapes.

Talk about savings!! First (and last) time ever going through anything like this, suddenly life was flipped upside down. 4 felonies, looking at potential federal prison, a life changed for good. Jon made things easy to understand. One of the first things he asked was what would be my ideal outcome, t...

Remarkable Criminal Defense Attorney
In 2021, I found myself facing serious felony charges that could have resulted in up to 8 years in jail. I was blindsided by the situation I found myself in, I had no criminal history and had no idea what my rights were. Thankfully, my wife previously worked in a neighboring law office and had kno...
