Proudly Serving Clients In State and Federal Courts Across California


Criminal Defense

As a former Deputy District Attorney and Deputy Public Defender, I have handled thousands of criminal cases ranging from infractions and misdemeanors to three-strikes cases and other serious/violent felonies, including serious sex crimes. I am also an experienced DUI and domestic violence defense attorney. I have assisted clients in drug court, domestic violence court, and veterans court. I also help clients address post-conviction issues, including violations of probation, appeals, and expungements. In the spirit of my prior public service, I also consider taking on "low-bono" cases already headed for trial.

Business Meeting

Civil Litigation

As a former corporate litigator at a prestigious "big law" firm, I helped large corporations battle other corporations. I now apply these same skills to help people resolve disputes with businesses prior to a lawsuit or to litigate all the way through trial, if necessary. These skills allow me to help individuals fight injustices against businesses that have taken advantage of them. I am also experienced in helping individuals in other civil (or quasi-civil matters), such as civil harassment restraining orders.


Personal Injury & Civil Rights

I am an experienced personal injury attorney who has helped others obtain full value for injuries caused by the negligence or wrongful conduct of others, including from serious collisions (car, truck, train, and bus), medical malpractice, excessive force and police brutality by law enforcement and other serious misconduct, wrongful death, elder abuse, and other cases in which a person has been injured or has died due to the fault, negligence, or misconduct of others.



I am a former Deputy District Attorney and Deputy Public Defender who has litigated thousands of cases, including misdemeanors and felonies. My background includes adult and juvenile cases, as well as serious and violent felonies, including sex crimes, and three-strikes cases. With these experiences, I know the criminal justice system from the inside.

I am also an experienced civil litigator with a litigation background at a "big law" firm. I later switched sides to sue corporations and other entities or persons (including insurance companies, police departments, governments, physicians, and others) on behalf of individuals to obtain justice for my clients. I have seen how corporations and the government fight to protect their interests, and I use those same skills to protect individuals against the injustices inflicted upon them. 

I am a member of several prestigious trial and attorney organizations. I am admitted in all state and federal courts in California. I graduated summa cum laude and Phi Beta Kappa with top honors from college. I later earned my MBA/JD from UCLA. I also have a graduate degree from USC.
