Passionate Criminal Defense in New Jersey and New York

Our criminal defense lawyers understand the confusion surrounding criminal charges. We will explain the process for any criminal charge, including:

  • Drug crimes: We represent those charged with possession of many types of drugs. Our drug law attorneys will assist with charges for marijuana, cocaine, heroin, methamphetamine, ecstasy, unlawful use of prescription medication, and many more drugs.
  • DUI/DWI charges: If you have been arrested for driving while intoxicated, our DUI lawyers will fight to help you keep your driver’s license and keep you out of jail.
  • Shoplifting: Our Parsippany attorneys defend clients charged with petty theft and retail theft.
  • Domestic violence: Often, Domestic Violence charges are issued without sufficient cause and without an opportunity for you to be heard before the Court prior to their issuance. There needs to be a correct basis for domestic violence charges. We will investigate the matter to ensure your rights are not violated and fight to lift restraining orders erroneously issued against you.

Whether you need help in municipal court or representation as a juvenile, we will provide the necessary guidance.
