Services
Criminal Defense
Our criminal defense practice handles all felony and misdemeanor charges, including drug crimes, DUI, and violent offenses. With specialized expertise in California criminal law, we develop tailored defense strategies to challenge evidence, negotiate plea deals, and litigate at trial when necessary. Our team's deep understanding of procedural law ensures comprehensive protection of clients' constitutional rights throughout the legal process.
DUI Defense
Specialized DUI defense includes challenging blood alcohol testing methods, field sobriety evaluations, and license suspension proceedings. We leverage technical knowledge of breathalyzer calibration and constitutional law to identify procedural errors that can reduce charges or secure dismissals. Our approach combines scientific analysis with aggressive courtroom advocacy to protect driving privileges and minimize penalties.
Expungements
We guide clients through California's expungement process to clear eligible criminal convictions from their records. This includes preparing petitions, demonstrating rehabilitation, and navigating court requirements for dismissed charges. Our service addresses probation completion verification, restitution compliance, and presenting compelling evidence to secure judicial approval for record sealing under Penal Code 1203.4 PC.
Restraining Orders
Our practice handles both restraining order defense and protection requests, addressing domestic violence, civil harassment, and elder abuse cases. We challenge unfounded allegations through evidence presentation while securing emergency protections for legitimate victims. The service includes court filing assistance, hearing preparation, and navigating complex intersections between criminal charges and civil protective orders.
Asset Forfeiture
We defend against government attempts to seize assets related to alleged criminal activity, including vehicles, cash, and real estate. Our approach challenges the evidentiary basis for forfeiture claims while negotiating alternative resolutions. We represent clients in both criminal forfeiture proceedings and related civil litigation, focusing on demonstrating lawful property ownership and absence of criminal connection.
