Firm Overview

Attorney David J. Grimaldi is committed to protecting the freedom of his clients and ensuring their constitutional rights. As members of a common society, we must not allow the government’s exclusive power to arrest people and incarcerate them go unchecked. History and common sense remind us that we must always hold the government to account, challenge its questionable claims, and fight its abuses of power. In the realm of criminal justice, the best way to secure a person’s liberty and protect individual rights is a strong, experienced, and dedicated criminal defense attorney.

Boston Criminal Defense Attorney David J. Grimaldi provides outstanding legal representation to individuals accused of crimes in state and federal court. He has successfully represented clients from across the state charged with nearly every kind of felony and misdemeanor offense. No matter the seriousness of the charge or the complexity of the case, Attorney Grimaldi has the proven ability to challenge the prosecution’s accusations and achieve the best possible outcome for his clients.

Attorney Grimaldi’s practice philosophy reflects who he is as a person: hard-working, loyal, principled, compassionate, innovative, and resilient. Attorney Grimaldi knows how important his cases are to the people he represents. He always gives personal attention to his clients, provides them with updates about their cases, answers their legal questions, and strongly advocates for them in court.

A skilled and fearless trial lawyer, Attorney Grimaldi thoroughly prepares every case and has a remarkable track record of “not guilty” verdicts at trial. Over his career, Attorney Grimaldi has tried dozens of cases in District, Superior, and Federal Court. He is an expert at identifying the weaknesses in the prosecution’s case and turning them into reasons for the jury to find his client “not guilty.” If a case can be won before trial, of course, we always count that as a success as well.

A Massachusetts native, Attorney Grimaldi is personally familiar with the people and communities he serves. He grew up in South Boston and Dorchester, attended high school in West Roxbury, went to college in Worcester, and graduated in 2007 from Boston College Law School. After seven years of trial experience at the public defender office in Suffolk, Essex, and Plymouth counties, in 2014 he opened a private law office in Cambridge from which he practices in state and federal courts throughout Greater Boston and Massachusetts. Attorney Grimaldi has the knowledge, experience, and character to provide you the vigorous defense that you deserve.
