Nassau County Traffic Violations & DWI Attorney
At Grunwald & Seman, P.C., we have extensive experience defending people against charges of driving under the influence (DUI), driving while intoxicated (DWI) and other traffic related offenses. Each of our attorneys have more than 25 years of experience in this practice area and honed their skills as prosecutors as well as in private practice. As a result of our experience, we've prosecuted and defended people against almost every kind of drunk driving and traffic violation charge there is in New York.
Over the years, we have developed skilled techniques for exposing flaws in the prosecution of these cases, including exposing mistaken or lying witnesses, and procedural errors. Through our knowledge of the science involved in blood and forensic pathology or our ability to analyze Breathalyzer testing and calibration, we are skilled in making sure the prosecution fails to prove their 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.
