Legal Services & Lawyers

I was a Deputy District Attorney for over 12 years prior to becoming a criminal defense attorney. I worked in Tulare and Orange Counties, prosecuting every type of criminal case, including driving under the influence, theft, three strikes, domestic violence, gang cases and homicides. I spent six years in the prosecution of serious sexual assault cases. For over a year, I worked closely with law enforcement in a narcotics task force assignment. That assignment included extensive work on search warrants and wiretap cases. I believe I have earned the respect of my colleagues in the District Attorney’s Office as well as with the judges I have appeared before. I have handled thousands of cases during all stages of criminal prosecution – from case assessment and the filing of criminal charges to trial and sentencing.

Before attending law school, I worked for over three years as a reserve Deputy Sheriff with the Los Angeles County Sheriff’s Department. During that time, I worked uniformed patrol and was involved in all aspects of criminal investigation, from traffic stops to bank robberies and homicide cases. During my time in the academy, I received honors as the top cadet in academics and firearms. I was also given the highest award and named Honor Cadet by the Sheriff’s Department.

In addition to being a trial lawyer, I have taught extensively on many aspects of the law. I currently teach all areas of criminal law at a state-approved police academy, including courses on search and seizure law, criminal interrogation and the laws of arrest. I also teach a course on homicide investigation at a local community college. I have trained other prosecutors during seminars for the California District Attorney’s Association (CDAA) in the areas of trial tactics and crimes against children.

After leaving the DA’s office, I opened my own practice, focused exclusively on criminal defense. As a solo practitioner, every client gets my personal representation - not a junior associate or an attorney unfamiliar with the facts.
