Antelope Valley:

We believe that everyone deserves the most aggressive and reliable criminal defense legal representation, and with over 50 years of experience as Criminal Defense Attorneys, we know that the Antelope Valley District Attorney and the Antelope Valley Police Department will use any tactic to strongly prosecute all criminal and DUI cases. As former prosecutors within Antelope Valley and as a "Pre-eminent" Top 5% Firm in the United States, we are personally familiar with the court officers assigned to the Antelope Valley Courthouse. This results in our Partners being frequently able to negotiate directly with the District Attorney to prevent your case from being formally filed, and therefore preventing it from being written to your permanent record.

The Criminal Courthouse is part of the North Judicial District of L.A. Count and is located at 42011 4th Street, Lancaster, California. The McCourtney Juvenile Justice Centers, for juvenile delinquency prosecutions, is located at 1040 W. Avenue J, Lancaster, California.

If you have been sued for any reason, or require legal counsel to conduct business or family legal matters contact my office immediately at (310) 503-6213. It is critical to obtain legal counsel sooner rather than later to avoid potential liability and mitigate damages.


If you have been arrested or charged with a violent crime, drug crime, DUI, theft or fraud, juvenile crime, endangerment, domestic violence, suspended license, bench warrant, probation violation, or any other misdemeanor or felony, contact my office immediately at (310) 503-6213. Remember to utilize your 5th Amendment right to remain silent and to consult with an attorney before speaking to anyone. I will explain the legal process to you and plan an aggressive defense starting with arraignment, bail issues, preliminary hearing and trial if necessary. Do not talk to any prosecutors!
