Personal Injury
We represent clients in serious personal injury cases resulting from auto accidents, wrongful death, and other negligence-related incidents. Our attorneys leverage decades of trial experience and relationships with medical experts to secure full compensation for medical expenses, lost wages, and emotional distress. With former prosecutors and a retired judge on our team, we combine courtroom prowess with strategic negotiation skills to maximize client recoveries.
Criminal Defense
Our criminal defense practice handles felony and misdemeanor cases including drug offenses, domestic violence, and white-collar crimes. As former deputy district attorneys with 250+ jury trial experiences, we understand prosecutorial tactics and leverage this insight to build robust defense strategies. Our team's unique combination of prosecutorial history and judicial perspective enables effective case resolution through negotiations or trial advocacy.
DUI Defense
Specializing in California DUI defense, we represent clients facing first-time offenses through vehicular manslaughter charges. Our attorneys employ former police investigators and breathalyzer experts to challenge evidence while leveraging decades of courtroom experience. With three former prosecutors on staff, we understand both sides of DUI cases and use this knowledge to minimize penalties or secure dismissals through strategic defense.
Wrongful Death
We assist families in recovering compensation for losses due to negligence-caused fatalities. Our attorneys handle complex cases involving auto accidents, medical malpractice, and product liability, seeking damages for funeral costs, lost income, and emotional suffering. With trial-tested attorneys and access to accident reconstruction experts, we build compelling cases to secure fair compensation for surviving family members.
Car Accidents
We represent clients injured in motor vehicle collisions, addressing insurance coverage issues and seeking compensation for medical bills and property damage. Our team handles uninsured/underinsured motorist claims and complex cases involving commercial vehicles or defective auto parts. With extensive trial experience and relationships with accident reconstruction specialists, we ensure clients receive full compensation for both economic and non-economic damages.
