Premier Massachusetts Criminal Defense Lawyers
At Carney, Gaudet & Carney, our priority is to give you The Best Defense. Our Massachusetts criminal defense attorneys work together as a team, investigating criminal allegations to the fullest extent. We listen to your goals to devise a criminal defense strategy based on what you find most important. We strive to empower you with the knowledge to make the best decisions.
With a combined six decades of experience handling complex criminal defense cases in Boston and across Massachusetts, the team at Carney, Gaudet & Carney is uniquely equipped to provide strong legal counsel and personalized representation tailored to your specific situation.
We advocate for clients facing all types of criminal charges and investigations: federal crimes, white collar crimes, drug crimes, violent crimes, sex crimes, domestic violence crimes, mental health related crimes, and more. Our legal team is skilled at guiding clients through both federal and state criminal investigations. We help our clients secure the best possible outcome in their cases by clearing their names, guiding them through the litigation process, securing more lenient outcomes in sentencing, and negotiating alternative resolutions to spare prison time or a criminal record.
Many criminal cases are not simply about the cases themselves. Criminal charges can risk a person’s professional licensure, career, and reputation. There are often other collateral consequences to a person faced with a criminal charge and their loved ones, such as adverse media exposure. We are experienced in handling all aspects of a criminal case and zealously advocate for our clients both in and out of the courtroom. We see it through to the end to ensure that a client’s record is either expunged or sealed, so that the charges do not harm their future.
We also counsel parents and students for campus disciplinary hearings, including Title IX sexual assault investigations and hearings, as well as hearings before the Sex Offender Registry Board and the Department of Children and Families. Our attorneys will follow through to fully protect your rights throughout the process, including in an appeal if one becomes necessary.
At Carney, Gaudet & Carney, criminal defense is all we do, so you can trust that no matter what your charges are, our attorneys will know how to handle them.

Every story has two sides, and we will believe your version of events. We devote extensive time to uncovering the truth about what really happened to create a reasonable doubt in the minds of the prosecutor, judge and jury. We also work with counseling experts to see if our clients can benefit from treatment in order to show that an act of poor judgment was a one-time event that is unlikely to be repeated. We defend clients throughout Massachusetts against domestic violence charges.
Drug and Firearm Cases
Drug trafficking and distribution offenses are serious felonies in Massachusetts — with equally serious punishments. The same is true for firearms crimes.
The best way to avoid these consequences is to hire experienced defense lawyers who will fight your charges and fight to protect your future.

We take the time to get to know your child — their strengths, weaknesses and struggles — and build their story into our defense. Everyone deserves a second chance.
A young adult should learn from mistakes, but one error should not ruin their opportunity to succeed.

Led by one of the most successful criminal defense attorneys in the state, we offer strong and strategic defense in court and in campus disciplinary hearings.
Expungement & Sealing
A criminal record can make it hard, if not impossible, to find a job or secure housing.
If you had plans to attend college or graduate school, or work in the medical profession, you will almost certainly face challenges.
We will fight to protect your future by sealing your criminal record, which removes it from public accessibility, or expunging it, which completely destroys the record. Our lawyers are experienced and can quickly determine if your record qualifies for expungement or sealing. Let us help you seek a positive outcome.
