Criminal Defense Attorney

I specialize in Criminal Defense. It is the only type of law I practice. The people I help range from juveniles to adults. Everyone deserves a vigorous defense, every case is important, and everyone deserves to be treated with respect. I do not judge my clients, I defend them.

In the State of New Jersey it is illegal to operate a motor vehicle when your blood alcohol concentration (BAC) is .08 percent or above.

I represent individuals charged with a variety of traffic offenses. I am proactive and strategic. I’ll help you to limit the negative consequences and protect your driver’s license.
