Aggressive DUI/DWI Defense for Northern California Clients

At Hansen & Miller Law Firm, we use our comprehensive knowledge of California DUI law and our combined 40 years of experience to make sure your constitutional rights are protected in the course of a traffic or DUI stop. (DUI can include alcohol, marijuana, Ambien, or another impairing agent.)

Former prosecutors Monte L. Hansen and Roy E. Miller understand the many ways in which a DUI/DWI arrest can go wrong. Factors that may work in your favor include road and weather conditions, a pre-existing medical condition or malfunction in your motor vehicle. We explore every avenue to free you of these charges.

Reach out to the Hansen & Miller Law Firm if you have been arrested for drunk driving in Sonoma County, Napa County, Mendocino County, Marin County or Lake County. We work hard to keep your driving record clean and preserve your driving privileges.

Call our fast-acting Santa Rosa DUI/DWI defense attorneys at 707-575-1040, or contact us by e-mail for immediate help when you are facing any serious offense.

From First Hearing to Final Outcome, You Can Trust Our Sonoma County Drunk Driving Defense Attorneys

Our skilled DUI/DWI defense attorneys protect your rights during every phase of your drunk driving case, including:

  • DMV hearings
  • Motions to suppress
  • Motions to dismiss or reduce charges
  • Examinations of illegal stops and probable cause
  • Validity of field sobriety, breath, blood and urine testing
  • Substance abuse treatment and rehabilitation, if necessary
  • Driving with license suspended or revoked
  • Uninsured and underinsured motorists in DUI/DWI accidents
  • Driver’s license revocation hearings
  • DMV hearings to reinstate driver’s license

We understand the negative impact a drunk driving conviction can have on your future — possible jail time, substantial fines, loss of your driver’s license, and the stress this creates on your family. If your livelihood depends on the status of your commercial driver’s license (CDL), a conviction could mean the end of your career.

You can trust our lawyers to be at their best when the stakes are high. We urge you to speak with our criminal defense law firm when a DUI/DWI arrest threatens your ability to get to your job and provide for your family.
