New Jersey Criminal Defense Attorney

Protecting Your Future

A criminal conviction can have long-term consequences. In addition to the possibility of spending time behind bars, you might lose your driver's license or pay excessive fines. A conviction could also negatively impact your job — your family — your reputation.

My name is John W. Hartmann. Since 1994, I have been vigorously defending people charged with a range of crimes, including theft and fraud, at my office in Princeton Junction, New Jersey. As your lawyer, I will work to prevent a criminal charge or conviction from damaging your future.

Scope of Criminal Defense Practice

As an experienced criminal defense attorney serving Mercer County and the surrounding areas, I can defend you against felony and misdemeanor charges, such as:

If you have already been convicted of a crime, I can handle your expungement case. Call my office at 609-897-1111 to schedule a free initial consultation.

In-Depth Knowledge of the Opposition

With years of experience practicing criminal defense, I know what strategies work against the opposition and which do not. When you hire me to defend you, you will benefit from my extensive knowledge.

Aggressively Fighting for You

A seasoned litigator, I believe in preparing every case as though it will go to trial. That means I will investigate the circumstances surrounding your arrest, interview witnesses and examine the prosecution's evidence. When appropriate, I will use a trusted private investigator to ensure all available information is gathered.

When Results Matter, Trust My Experience

To discuss how I can defend you against any criminal charge, contact me online or call my office at 609-897-1111. I serve clients in Mercer County and the surrounding areas.

Special hour appointments are available. Credit cards are accepted.
