Experienced New Jersey Criminal Defense Lawyer

When You Need a Smart and Aggressive Defense

When you've been charged with a crime — any crime — it can feel like the world is against you. Although the law instructs that you are innocent until proven guilty, the police, investigators and even the court of public opinion often seem to presume your guilt. If you have been accused of a crime, you need an experienced criminal defense attorney to stand up for your rights.

My name is John W. Hartmann. At my office in Princeton Junction, New Jersey, I have been aggressively defending people accused of misdemeanor and felony crimes ranging from murder, gun offenses, and DUI/DWI since 1994. I will handle your case at any stage — whether you are preparing for trial or seeking an expungement.

Former Prosecutor Providing Vigorous Criminal Defense

Choosing which lawyer will defend you against criminal charges is an important decision. The right attorney can make a significant difference in the outcome of your case. Experience, skill and knowledge of the opposition are invaluable.

Before dedicating my legal career to criminal defense, I served as a municipal prosecutor. Therefore, I understand how the opposition thinks and prepares. I know what works against the prosecution and what doesn't. This in-depth knowledge helps me build strong defense strategies for my clients.

Doing What It Takes to Fight for You

Some attorneys prefer to settle legal disputes outside the courtroom. However, I believe a lawyer should be prepared to take every case to trial. I have been involved in over 40 trials in 15 years and have a proven track record of success.

A thorough investigation into your arrest helps me build a strong defense for you. To ensure I gather the proper evidence, I use the services of a trusted private investigator when appropriate.
