Criminal Defense Attorney in Scottsdale

DUI, Drug & Vehicular Crime Defense Grounded in Prosecutorial Experience

I founded The Koplow Law Firm in 2005 after working as a prosecutor, where I learned firsthand how the state builds its cases. That background shapes every defense I craft. I know which arguments the DA’s office relies on, where forensic evidence gets overstated, and where cases develop real weaknesses. My practice focuses on defending people facing DUI, drug-related, and vehicular crime charges in Scottsdale and throughout Maricopa County.

Nearly two decades in criminal law have sharpened my instinct for what matters in these cases. My mission has always been straightforward: defend your dignity, protect your liberty, and help you reclaim control of your life when the justice system feels overwhelming.

If you’re facing criminal charges, call me now at (602) 560-7837 for a free consultation. I’m available 24/7 and offer virtual meetings for your convenience.

Recognition That Reflects a Focused Practice

The Arizona Attorneys for Criminal Justice (AACJ) honored me with their Outstanding Contribution to DUI Defense Award in 2015 and their President’s Commendation. Southwest Super Lawyers recognized me in 2019. These aren’t marketing credentials. They reflect a sustained commitment to a specific, demanding area of law.

My prosecutorial background doesn’t just inform strategy in the abstract. It lets me anticipate what the state may argue, identify assumptions worth challenging, and spot the gaps that a less experienced defense attorney might miss entirely.

How I Approach Every Case

Criminal defense isn’t one-size-fits-all, and I don’t treat it that way. Every case I take receives a defense built around the specific facts, the specific charges, and the specific person in front of me. When you hire The Koplow Law Firm, you work directly with me. Not a junior associate. Not a paralegal who passes messages. Me.

My forensic training in DUI science, vehicular crimes, and complex drug cases lets me examine evidence at a level of detail that makes a real difference. I’ve trained attorneys across Arizona and in other states on how to handle these charges, which reflects how deeply I understand this territory. When the justice system fails to protect a client’s constitutional rights, I push to correct that failure, for the client in front of me and for the integrity of the system itself.

I also don’t judge the people I represent. Everyone who comes to me is a person who needs help navigating a difficult moment, and I treat them that way from the first conversation.

Criminal Charges I Defend in Scottsdale

My practice is deliberately focused. I defend clients facing the following charge types:

DUI Charges
From standard DUI to aggravated DUI, including cases involving alleged impairment by alcohol, prescription drugs, or controlled substances.

Drug-Related Charges
Possession, possession for sale, transportation, and related offenses involving marijuana, prescription drugs, and other controlled substances.

Vehicular Crime Charges
Vehicular homicide, vehicular assault, endangerment, and leaving the scene of an accident.

Why Handling DUI, Drug & Vehicular Crimes Together Matters

In Arizona, these charges rarely stay neatly separated. A DUI stop can produce drug possession charges. A vehicular accident can lead to both DUI allegations and vehicular assault charges in the same case. When a defense lawyer handles only one of these areas, the defense can miss how the charges interact.

Because my practice covers DUI, drug-related offenses, and vehicular crimes as an integrated body of work, I bring overlapping forensic and statutory knowledge to cases where these charges intersect. That integration shapes strategy in ways that matter when prosecutors are building a case from multiple angles.

    "Great trial attorney."

    Lawrence is tenacious, relentless, and extremely passionate about his clients and their cases. He leaves no stone unturned in his investigations, and his cross examinations are grueling. His knowledge of the science of DUI's and the testing procedures is unsurpassed. Great trial attorney.

    - 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.
    - Ryan M.
    "You cannot go wrong with Lawrence."

    Great attorney! Lawrence thinks outside the box and goes above and beyond for his clients and the legal community at large. If you are looking for aggressive representation, you cannot go wrong with Lawrence.

    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.

    - Joe C.
    "One of the best."
    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.

    "Nobody knows the court and laws better than him."
    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.
    - David E.
