Experienced NJ DWI Lawyers and Former Prosecutors

Our lawyers form the largest, most credentialed DWI team in the state. We have lawyers who were former prosecutors in 25 municipalities and several counties. Some of our lawyers have more than 35 years of experience, others more than 20 years of experience.

Our significant experience gives us solid judgment about whether to fight the charge or negotiate the best result we can for a client. It helps us choose and execute the most effective method of defending against the charge. But we offer more than just experience. We have a deep commitment to helping our clients improve the results of their DWI charge.

  • Three lawyers at our firm are certified to maintain and operate breath test machines.

  • Three attorneys at our law firm are certified to provide field sobriety tests.

  • Three lawyers are certified field sobriety test instructors.

This training allows us to look closely at police work in your case and to explore all possible angles for challenging evidence in your case. Suppressing a breath test in your case can mean the difference between a conviction and a dismissal, a license suspension or being able to drive freely through the state.
