Meet Mario Martinez Jr.


Superior Court Judge Nominee

I was born in 1965 at Kaiser Hospital in Fontana and grew up in Chino. Like my grandfather, aunts, uncles, and cousins I attended Chino schools and graduated from Don Lugo in 1983. After high school, I attended Cal Poly Pomona and played one season on the junior varsity baseball team. During my years at Cal Poly, I studied history and volunteered as a baseball coach at Chino National Little League and at Don Lugo High School.

In 1988, I graduated with a B.A. in history and continued my studies at the University of California, Hastings College of the Law in San Francisco. I graduated in 1991 and was admitted to the bar the following year. As a young attorney, I volunteered at Legal Aid Society of the San Gabriel Valley helping people facing eviction. In 1994, I enlisted in the United States Army Reserve and served 8 years reaching the rank of sergeant when I received my Honorable Discharge in 2001.

From 1995 to 2000, I worked in private practice which included personal injury, plaintiff and defense, family law, and criminal defense. At this time, I continued to coach little league baseball and I taught paralegal studies at LA’s Southwest Junior College.

In 2000, I became a Deputy Public Defender for the County of San Bernardino and I have been there since. During my career, I have handled 1,000s of cases and have completed numerous trials. As a public defender, I learned how to effectively speak to my client and their families as I assisted them through the criminal justice system. I also learned how to work, respect, and admire court staff, sheriff’s deputies, police officers, district attorneys, and judges. Now, I would like to continue serving this community as a superior court judge and I am asking for your support.

Judicial Qualifications

Three Pillars of Justice







"If elected, I would not only be fair but I would treat the people who came into my courtroom with respect and dignity"

Mario Martinez Jr.


For the last 20 years, I have vigorously defended individual rights here in San Bernardino County. As a Deputy Public Defender, I have learned to listen to people and to communicate with all sides. I believe respect is equally important in speaking to clients, court staff, opposing counsel and of course the judge. As a defense attorney, I strove to argue facts and not make anything personal, and to conduct myself in a professional manner.


As a judge, I believe I have the life experiences to be fair and equitable. In my family, we have police officers, probation officers, correction officers, and attorneys. We also have a stockbroker, teachers, UPS drivers, a restaurant manager, business owners, construction workers, and steelworkers. In fact, my father and uncles retired from Kaiser Steel in Fontana. I have a large family with many different views and opinions yet despite our differences we manage to keep in touch and spend time together.
