About me

I have over eight years of experience as an attorney in the Southern California courts.  I also have another three years experience inside the District Attorney's Office as a law clerk.  I worked as a Deputy District Attorney in Riverside County for  four years before heading into private practice. I have tried numerous cases both as a prosecutor and defense attorney. I work hard and am a zealous advocate for my clients.
