Practice Areas
The firm handles the full range of criminal defense matters in Camden County and Southern New Jersey.
DWI Defense
DWI cases in New Jersey require specific technical knowledge about the Alcotest 7110, the breathalyzer device used by New Jersey law enforcement. The firm employs a certified Alcotest 7110 operator, providing an internal technical resource for challenging breath test results and the procedures used to administer them. This is a meaningful capability in DWI defense that most firms cannot match in-house.
Drug Crimes
The firm defends clients charged with drug possession, distribution, and related offenses across Camden County and Southern New Jersey. Attorneys who previously prosecuted drug cases for the state understand how those cases are built and where they can be effectively challenged.
Sex Offenses and Weapons Violations
Sex offense charges and weapons violations carry serious long-term consequences beyond incarceration. The firm handles both categories, applying the same prosecutorial insight that informs its approach to other serious charges.
Theft, Assault, and Juvenile Matters
Theft charges, assault cases, and juvenile matters are all within the practice’s scope. The firm’s experience prosecuting and defending these charges gives its attorneys a three-dimensional understanding of how cases are presented and where defense opportunities exist.
Serious Felony Defense
Cases involving attempted murder, aggravated assault, and homicide require the highest level of criminal defense capability. The firm’s former prosecutors previously handled these charge categories for the state, and that direct experience informs how they approach defense of the same charges.
