After almost 20 years as a prosecutor, Mr. Anderson brings to the Law Offices of Thomas C. Mooney extensive experience in complex, high profile criminal matters, especially matters involving homicide, violent crimes, and vehicular crimes.

In 2003, Mr. Anderson began his career as an Assistant District Attorney in the Kings County District Attorney's Office in Brooklyn, New York. Mr. Anderson was assigned to the "Red Zone" which was the most violent and busiest division in the office. Mr. Anderson's primary assignment was violent crimes ranging from Robberies to Homicide. Mr. Anderson was cross designated with the Vehicular Crimes Division where he handled repeat DWI Offenders and Vehicular Manslaughter cases. During his time in Brooklyn, Mr. Anderson was promoted to Senior Trial Attorney for conducting dozens of felony and countless misdemeanor jury trials.

In 2008, Mr. Anderson joined the Montgomery County State's Office as an Assistant State's Attorney. During his time in Montgomery County Mr. Anderson was assigned to the Down County Felony Division, Special Victim's Investigation Division, Major Crimes Division, Manslaughter by Motor Vehicle Team and the General Felony Unit as a Deputy Team Leader.

How do I choose a lawyer?

Consider the following:

Comfort Level
- Are you comfortable telling the lawyer personal information? Does the lawyer seem interested in solving your problem?

- How long has the lawyer been in practice? Has the lawyer worked on other cases similar to yours?

- How are the lawyer's fees structured - hourly or flat fee? Can the lawyer estimate the cost of your case?

- Is the lawyer's office conveniently located?

Not sure what questions to ask a lawyer?

Here are a few to get you started:

  • How long have you been in practice?
  • How many cases like mine have you handled?
  • How often do you settle cases out of court?
  • What are your fees and costs?
  • What are the next steps?

Want to check lawyer discipline?

It is always a good idea to research your lawyer prior to hiring. Every state has a disciplinary organization that monitors attorneys, their licenses, and consumer complaints. By researching lawyer discipline you can:

  • Ensure the attorney is currently licensed to practice in your state
  • Gain an understanding of his or her historical disciplinary record, if any.
  • Determine the seriousness of complaints/issues which could range from late bar fees to more serious issues requiring disciplinary action.
