About Me

I grew up knowing I was going to be a defense attorney.  I never conceived of any other profession.  Once  I started practicing criminal defense, I found that while any lawyer will take a DUI case, few had dedicated the time and effort to learning the science well enough to look for possible defenses in almost any case.  Instead, they just got good at telling their clients they needed to plead guilty without thouroghly evaluating the case.  I do my best to never let that happen with my clients' cases.

  • Bradley R Corbett

    The top DUI Lawyer in San Diego. I call Jon whenever I have a question about a DUI case. He is unbelievable in court. He is an aggressive advocate for his clients and gets great results. I would have Jon represent me if I got a dui.

  • Daniel Martin Smith

    John is by far the best DUI lawyer in San Diego County and Southern California that I know. I have witnesses acquittals that seemed impossible. Dismissals that I did not see coming. He leaves no stone unturned and he is remarkable. Prosecutors truly fear him because they understand that he knows DUI law inside and out. Most of all, juries like John's understated intellligence and self effacing humor. The juries love him, and nothing scares a prosecutor more than a likeable, witty and intelligent lawyer. I endorse John for any DUI case, period.
