About me


I am proud to lead a team of four dedicated lawyers, each trained in DUI defense.  Together, they have litigated thousands of DUI cases in courtrooms throughout Southern California and before the DMV.  They have taught and written extensively on the law and science of DUI and collectively represent the most respected and recognized leaders in DUI defense.  The team is made up of four (4) lawyers, specially trained paralegals and investigators. Our firm also provides access to the top experts in forensic toxicology and Pharmacology who closely work with us to analyze the important scientific issues that are relevant to your DUI case.
