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.

Arizona DUI Lawyer

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.

    Mr. Koplow is uniquely qualified to handle DUI/vehicular crime cases. He is a former DUI prosecutor with the Maricopa County Attorney’s Office. At the time he left the County Attorney’s Office, he was working in the Maricopa County Attorneys’ Vehicular Crimes Unit. Mr. Koplow was then chosen by one of the largest insurance companies in America to work in its in-house counsel group. As counsel for Farmer’s Insurance, he primarily handled the defense of automobile accident cases. This included defending civil lawsuits arising out of vehicular crimes. This combination of specialized knowledge and experience have given him a rare skill set for successfully defending impaired driving cases.


    Mr. Koplow subsequently founded the Koplow Law Firm, where his criminal practice is focused on DUI and vehicular crimes (charges involving vehicular homicide, vehicular assault, endangerment and leaving the scene of the accident, Misdemeanor DUI and Felony DUI.)


    As an attorney who exclusively practices DUI defense, Mr. Koplow has developed a vast network of experts (including forensic toxicologists, accident reconstructionists, biomechanical engineers and ophthalmologists) to assist in the defense of his clients’ cases. Using the right expert can be critical to developing the best DUI defense.


    In addition, Mr. Koplow is on the cutting edge of DUI defense. He is creative in his methods and is responsible for bringing about new and extraordinary techniques in the defense of DUI cases. Moreover, Mr. Koplow reviews the latest cases, scientific literature, legal treatises and articles on the subject of DUI / drunk driving defense.


    Mr. Koplow has earned a reputation as a skilled trial Arizona DUI attorney. His philosophy is to aggressively defend his clients. He understands that anyone can receive a DUI charge. He believes that DUI cases are the best examples of good people caught on their worst days. With this mindset, Mr. Koplow will provide an aggressive defense to your DUI charge.

What Real People Are Saying

That is, DUI cases actually dismissed. Verifiable not guilty verdicts. Blood alcohol evidence truly suppressed as witnessed by judges, other lawyers, and newspapers.

REAL CLIENT, PHOENIX, AZ

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."

Measuring is different from counting. However, in forensic science the two are often suggested to be the same. This needs to change. MEASURING Measuring is the assignment of a number, and all the uncertainties of that of that number, to something.  The purpose of assigning a number is to give meaning to the object measured.
