Flagstaff DUI Lawyer Ready to Protect Your License and Your Future

A DUI Arrest Can Turn Your Life Upside Down — But You Still Have Options

Being arrested for DUI in Flagstaff can feel terrifying. You may be facing jail time, fines, license suspension, ignition interlock requirements, and a criminal record that follows you for years. It’s normal to feel overwhelmed — but a DUI charge is not a conviction. With the right defense strategy, you may be able to reduce penalties, protect your record, or even beat the charge entirely.



Arizona has some of the toughest DUI laws in the country. Acting quickly gives you the best chance at a positive outcome, especially because you have only 15 days to challenge your license suspension with the MVD.

What We Help With

First-Time & Repeat DUI Charges

Whether it’s your first offense or a second/third DUI, we pursue every avenue for reducing penalties, securing alternative sentencing, and protecting your driving privileges.

Extreme DUI & Super Extreme DUI

High BAC levels bring harsher penalties — but not all tests are accurate or admissible.

Underage DUI (NAU Students & Visitors)

Zero-tolerance laws apply to those under 21. We help young drivers avoid consequences that could affect school, scholarships, and career opportunities.

DUI on Federal Land (Grand Canyon, Lake Powell, Forest Roads)

If arrested on federal property, your case may go to federal court. Our federal license gives you a critical advantage.

Drug-Based DUI & Prescription Medication DUI

You can be charged even without alcohol in your system. These cases involve different testing and defenses.

MVD Hearings & License Protection

You have just 15 days to request a hearing to fight an automatic suspension. We handle all filings and represent you before the MVD.

Mistakes That Can Make a Tough Situation Much Worse

  • Waiting too long to hire a lawyer.
    Deadlines move quickly in DUI cases — especially with MVD.


  • Assuming the case is hopeless because of a high BAC.
    Breath and blood tests can be flawed, mishandled, or inadmissible.


  • Talking to police or prosecutors without counsel.
    Anything you say may be used against you.


  • Failing to request the MVD hearing in time.
    Missing this deadline can automatically suspend your license.



  • Pleading guilty too early.
    There may be strong defenses that aren’t obvious from the police report.

How We Build a Strong DUI Defense

Arizona DUIs are highly technical cases involving police procedures, scientific evidence, and constitutional rights. We examine every angle to find weaknesses in the state’s case.



Working With Our Firm:

01

Initial Consultation & Case Review

We evaluate the traffic stop, field tests, police conduct, and chemical testing.

02

Challenge to the Stop & Arrest

If there was no legal basis for the stop, evidence may be thrown out.

03

Analysis of Breath & Blood Tests

Machines malfunction. Calibration lapses. Chain-of-custody errors undermine results.

04

MVD Defense Preparation

We fight to save your license and secure driving privileges.

05

Negotiation or trial

We pursue reductions, alternative sentencing, or trial when it’s in your best interest.

If You’re Not Sure What to Do Next

If this is your first DUI

We explore reduced charges, diversion-like options, and strategies to minimize jail and protect your record.

If your BAC was high or the officer said you “failed” tests

We challenge the evidence — Flagstaff’s altitude, machine issues, weather, and officer error can all impact results.

If you rely on your car for work or family

We act immediately to preserve driving privileges through MVD hearings and restricted license options.

If you’re an NAU student or out-of-state visitor

We help protect your academic standing or ability to return home without court complications.

If your arrest happened on federal land

We guide you through the federal process and represent you in federal court.

Common Questions About DUI Defense in Arizona

  • How can I beat a DUI in Arizona?

    By challenging the stop, the testing methods, officer procedures, or chemical evidence. Many cases result in reductions or dismissals.

  • Will I lose my license?

    Possibly — but you have 15 days to fight the automatic suspension. We handle the MVD hearing for you.

  • What happens for a first-time DUI in Flagstaff?

    Arizona mandates jail time, but alternatives, reduced charges, or minimized penalties may be available.

  • Do I have to appear in court?

    Often yes, but we can sometimes appear on your behalf depending on the charge.

  • What if I blew over the limit?

    BAC numbers aren’t always reliable. Machines malfunction, blood samples degrade, and procedures get botched.
