Western Wisconsin Premier Dedicated OWI Defense Firm

When you are arrested for drunk or drugged driving, general criminal defense representation is simply not enough. Located on South Barstow Street in Eau Claire, Nero DUI Defense, S.C. is the only law firm in Western Wisconsin devoted one hundred percent to OWI and DUI defense. Founded by attorney Adam P. Nero, the practice offers an unmatched level of scientific and tactical mastery in operating while intoxicated litigation. Adam Nero is board-certified in DUI defense through the National College for DUI Defense, an elite distinction held by only a handful of lawyers nationwide. If you need to hire an OWI defense lawyer who understands the forensic science of chemical testing and courtroom litigation, this firm delivers focused, uncompromising advocacy.

Advanced Scientific and Forensic OWI Defense

Drunk driving prosecutions rely heavily on scientific instruments and standardized protocols that law enforcement officers often execute incorrectly. Attorney Adam Nero has completed rigorous training at Harvard Law School through the NCDD and studied forensic chromatography and blood drug analysis. This rare technical background allows the firm to uncover critical evidentiary flaws across all types of impaired driving cases, including:

• Challenging blood draw procedures, chain of custody violations, and hospital lab testing errors.
• Dissecting Intoximeter EC/IR II breath testing machines for calibration drift, radio frequency interference, and slope detector faults.
• Presenting disconnect defenses where observable physical sobriety directly contradicts high machine printout numbers.
• Cross-examining arresting officers on improper administration of standardized field sobriety testing.
• Defending complex drugged driving charges involving prescription medications and controlled substances.

Commercial Driver License and Repeat OWI Defense

For commercial driver license holders, even a first OWI arrest in a personal vehicle triggers a mandatory one-year CDL disqualification, threatening your career and livelihood. For individuals facing second, third, or fourth-offense felony OWI charges, Wisconsin law mandates harsh jail sentences, steep fines, and lifetime revocations. Nero DUI Defense moves immediately to request administrative hearings within ten days of arrest, seeking to preserve operating privileges while constructing comprehensive defense strategies for trial or negotiation.

Statewide Appellate and Post-Conviction Advocacy

Having represented clients across more than sixty Wisconsin counties, Adam Nero also accepts complex appellate matters before the Wisconsin Court of Appeals and the Wisconsin Supreme Court. The firm routinely challenges unconstitutional vehicle stops, coercive blood draws, and improper trial court rulings to reverse unlawful convictions and protect constitutional rights statewide.
