Nassau County Traffic Violations and DWI Defense Attorney
At Grunwald & Seman, P.C., we have extensive experience defending people against charges of driving while intoxicated (DWI) — sometimes called driving under the influence (DUI) — and other traffic-related offenses. Each of our attorneys has more than 25 years of experience in this area, and both honed their skills as prosecutors prior to entering private practice. We have prosecuted and defended people against almost every kind of drunk driving and traffic violation charge on the books.
Over the years, we have developed many techniques for exposing flaws in the prosecution of these cases, including procedural errors and mistaken or lying witnesses. Through our knowledge of the science involved in blood and forensic pathology, along with our proven ability to analyze Breathalyzer testing and calibration, we take advantage when the prosecution fails to prove its case beyond a reasonable doubt.
Our DWI defense lawyers are available 24 hours a day, seven days a week. For your free initial consultation, call 516-248-8889 or toll free 800-399-7098 now. Every minute counts — so don't delay.
