About Koplow Law Firm

Experienced in Phoenix DUI Law, Experienced in Winning

BASED IN PHOENIX, SERVING ALL OF ARIZONA

A DUI is a hammer. Want to avoid being the nail?  Then you've come to the right place. If you are reading my About page, it probably means you, or someone you care for was charged with an Arizona DUI or some kind of Vehicular Crime. Something you never imagined would, or could, ever happen. That makes you just like my typical client - A good person who had a really bad day.

Let's Fix This

My job is to try and make the pain go away. Sometimes that means getting a case dismissed, evidence suppressed, or persuading a jury to let my client go free. And many times it simply means dulling the pain. I do everything possible, and a few things that many lawyers didn’t even know were possible in DUI cases, to protect you.

What I Do For Real People

I am an Arizona DUI attorney who reveals the truth about flawed forensics that look flawless. When the justice system fails to protect people’s constitutional rights, I push to fix those failures. I challenge the status quo.  I regularly, and successfully, do this for people in DUI and Vehicular crimes cases. I do these things, so my clients can restore their dignity. To protect their liberty. To get their life back.

No lawyer can do this in every case, but if anyone can do it for you… I can.

    - Jesse S.
    "Unquestionably one of the top DUI/ criminal defense attorneys in Arizona."
    As a practicing attorney in DUI and criminal defense, and as a former prosecutor who went against Lawrence on several cases, I can attest that the State knows they will have their hands full when Lawrence is on the case.

    Lawrence is the best lawyer I have ever met. If your career is on the line then he is the guy. No other lawyer knows the science of DUI like Lawrence does. I will be forever grateful!
    - Greg S.
    "It was miracle!"

    It was miracle!... A lot of people don't really understand the benefit of having an attorney who used to be a prosecutor. They know all the little tricks and scare tactics the state has as opposed to just hiring an attorney who is a little fish in a big pond.

    Lawrence Koplow is one of the best DUI and vehicular defense attorneys in the state of Arizona. Anyone would be extremely fortunate to have him as their advocate.

    Lawrence represents very high-profile clients who greatly depend on a good outcome, and this guy will deliver. This is a prosecutors' worse nightmare, and it should be that way if you need an attorney.
