The Law Offices of Diego E. Ortiz provides aggressive, bilingual criminal defense across Alameda and Contra Costa counties, bringing more than thirty years of courtroom experience to drug crimes, violent felonies, domestic violence, DUI and DMV hearings, and record expungements.

Steadfast Criminal Defense in Oakland and the East Bay

Since establishing his Oakland practice in 1993, Attorney Diego E. Ortiz has defended thousands of clients against criminal accusations across Northern California courts. A graduate of Golden Gate University School of Law admitted to the California Bar on his first attempt in 1991, Ortiz continues a family legal tradition dating back centuries. Admitted to practice in California state courts, federal courts, and the Ninth Circuit Court of Appeals, he focuses exclusively on criminal defense. When individuals need an attorney who will stand beside them in court, Diego E. Ortiz delivers vigorous advocacy, straightforward counsel, and full bilingual representation in English and Spanish.

Vigorous Defense Against Drug Accusations

Drug offenses in California involve severe penalties depending on substance classification and quantity. Serving as experienced drug crime defense lawyers, the firm defends clients facing charges of simple possession, possession for sale, transportation, cannabis cultivation, and federal drug trafficking. Diego Ortiz investigates police conduct, challenging wiretaps, informant credibility, and unlawful vehicle searches to protect clients from unjust convictions.

Aggressive DUI and DMV License Defense

An arrest for drunk or drugged driving triggers immediate criminal charges and administrative driver's license suspension. As proven DUI/DWI defense lawyers, the office acts within the ten-day deadline to request DMV hearings and stay license suspensions. Diego Ortiz scrutinizes breath and blood test accuracy, disputes unlawful traffic stops, and challenges prior convictions to minimize penalties and preserve driving privileges.

Compassionate Domestic Violence Defense

Domestic dispute accusations frequently stem from heated arguments, divorce conflicts, or false allegations. Practicing as dedicated domestic violence lawyers, the firm defends clients against spousal abuse, criminal threats, and restraining order violations. The office works to protect family ties, challenge fabricated claims, and pursue pretrial diversion whenever eligible.

Violent Crimes and Strike Offenses

Under California's Three Strikes law, violent crime convictions carry catastrophic penalties. Acting as experienced violent crime defense lawyers, Diego Ortiz defends clients charged with assault with a deadly weapon, robbery, burglary, kidnapping, and manslaughter. By uncovering evidence and asserting self-defense, the firm fights to dismiss strike allegations and secure favorable verdicts.

Theft, Burglary, and Property Crimes

The firm acts as dedicated theft and burglary defense lawyers representing clients charged with grand theft, commercial burglary, and identity theft. The defense team identifies evidentiary weaknesses regarding criminal intent, negotiating civil compromises or reductions from felony to misdemeanor charges under California law.

Accessible Representation and Expungement Relief

Beyond active criminal charges, Diego E. Ortiz helps clients clear past records through expungements and probation terminations. To keep representation affordable, the firm offers flexible payment plans. Those seeking to find a lawyer with three decades of trial experience can consult a lawyer at his 1300 Clay Street office in Oakland. When you need to hire an attorney who treats clients with genuine care, Diego E. Ortiz delivers trusted legal support.
