Michael J. Silveira Had a Front-Row Seat to Thousands of Criminal Cases—Then He Built His Defense Playbook

A DUI or traffic prosecution can look deceptively standardized: a police report, a test result, a citation, and a court date. But the difference between a conviction and a dismissal can live in the details—the legality of the stop, the reliability of the evidence, the officer’s testimony, or a procedural weakness hiding in plain sight. Michael J. Silveira has built his career around finding those details.

Silveira’s courtroom education began before he entered private practice. As a volunteer with the San Francisco Public Defender’s Office, he directly participated in or co-chaired more than 15 jury trials, most reportedly ending in hung juries or not-guilty verdicts. He later served as a judicial assistant in the San Mateo County Superior Court, where he observed thousands of DUI and criminal cases from an unusually revealing vantage point. His professional biography describes him evaluating which arguments succeeded, recording effective courtroom approaches, and speaking directly with judges about what worked and why.

That practical foundation was matched by an impressive academic record. Silveira earned his law degree with honors from Golden Gate University School of Law, graduating within the top eight percent of a class of more than 250 students. He wrote and edited for the Law Review, earned the Witkin Award for the highest grade in Evidence, and received a CALI Award for Excellence in Real Property.

Since becoming principal attorney of Silveira Law, he has concentrated heavily on DUI defense, criminal charges involving automobiles, traffic violations, and DMV proceedings. Silveira reports personally handling more than 1,000 DUI cases and 500 additional criminal matters, while his firm reports serving more than 10,000 clients. His continuing focus on DUI defense includes membership in the National College for DUI Defense and the California DUI Lawyers Association, along with participation in advanced standardized field-sobriety-testing training.

The outcomes reveal why that concentrated experience matters. In one particularly difficult DUI case involving fentanyl evidence, Silveira continued fighting for more than three years after prosecutors reportedly refused to reduce or dismiss the matter. The case was ultimately dismissed completely. In another case, he secured dismissal of an Oakland DUI without requiring the client to accept a reckless-driving conviction.

His traffic-defense results are equally striking. Silveira obtained dismissal of a citation alleging a speed of 106 mph, protecting the driver from potential exposure to two DMV points, a 30-day license suspension, and a substantial fine. His published case history also includes felony charges reduced to a single misdemeanor with no jail, originally filed criminal charges dismissed in favor of one Vehicle Code infraction, and not-guilty verdicts that protected clients from serious licensing consequences. Past results cannot guarantee a future outcome, but they demonstrate the range of consequences his work has helped clients avoid.

Client feedback adds another dimension to that record. Silveira Law maintains a 4.9-star Google rating across 115 reviews—a meaningful volume of public feedback for a practice handling stressful, reputation-sensitive cases. Clients frequently describe dismissals, reduced charges, preserved driving privileges, and the ability to resolve matters without personally appearing at repeated court dates.

Silveira’s appeal is not built around one oversized verdict or a theatrical courtroom persona. It comes from repetition, specialization, and a career spent studying how criminal and traffic cases are actually won and lost. For consumers facing a system that can affect their freedom, license, employment, and future, that kind of disciplined experience carries genuine weight.

That combination of experience, reputation, verified professional standing, and public credibility is why Michael J. Silveira was included on FreddieFender.com.
