DWI Defense Lawyer ∙ Former Nassau County Prosecutor

If you or a loved one has been arrested for drunk driving (DWI), we strongly recommend getting a lawyer on your side as soon as possible. The sooner we get to work on your case, the sooner we can begin to protect your rights.


Our law firm can investigate your DWI arrest to see if the police violated any procedures. If they did, we can often get the charges reduced or the case dismissed.
Your DWI defense lawyer can challenge the results of breathalyzer tests, blood alcohol concentration tests (BAC) or other sobriety tests.

Mr. Kephart can negotiate for a lesser charge (reckless driving, for example) or help you with related charges. If a traffic violation was added to the charge, or if you are facing a drug charge related to the stop, we can represent you.

We can work with you to protect your driving privileges by scheduling an early DMV hearing.
If this is your first offense, second offense, third offense or more, you will want a defense attorney who will work hard to limit the consequences of your arrest.

Mr. Kephart will make his years of experience work for you. Contact our office at 516-459-3196 for a confidential consultation and let us give you peace of mind.
