About Me

Mr. Mastro grew up around the Bay Area. He graduated from the Santa Clara University School of Law. He sat for and passed the California State Bar Examination on his first attempt.


Thereafter, Mr. Mastro became a Deputy Public Defender in San Joaquin County (Stockton, Tracy), representing indigent clients in all manner of criminal cases.


After opening his own criminal-defense law practice, Mr. Mastro partnered and teamed with Mr. Nino to bring clients as comprehensive and vigorous a representation as possible.


Mr. Mastro is a member of the Alameda County Bar Association Criminal Court Appointed Attorneys Program, through which he represents indigent clients in all of the criminal courts of Alameda County. He has represented thousands of clients, with exceedingly positive results.


He is licensed and insured to practice throughout California, as well as in the federal courts of the Northern District of California.


Mr. Mastro enjoys life enough to understand that it is his job to get his clients back to their lives as quickly as possible.

    Joe was an exceptional public defender in San Joaquin County with thousands of cases to his credit. I personally saw the results that he achieved for an often ungrateful clientele. He genuinely cares for his clients and offers an impressive defense. Do yourself a favor and schedule a consultation with him first if you are in or near Oakland and need an aggressive defense.
