    Attorney Profile

    David J. Grimaldi founded his eponymous professional corporation in July 2014. Since that time, he has continued to focus his practice exclusively on criminal defense matters, representing clients throughout Middlesex, Norfolk, Suffolk, and Essex counties from the firm’s offices in Cambridge, Massachusetts. Mr. Grimaldi obtained his legal education at Boston College Law School, where he participated in regional and national mock trial competitions before obtaining his Juris Doctor in 2007. Prior to law school, he attended Clark University in Worcester, and he majored in European history and received a Bachelor of Arts magna cum laude in 2001.

    Mr. Grimaldi’s clients are area residents and others who have been charged by the Commonwealth or by the federal government with the commission of felony or misdemeanor offenses. The cases that he has worked on have included rape and other sex crimes, armed and unarmed robbery, homicide, weapons violations, child pornography, assault and battery, weapons violations, white collar crimes, and drug possession and trafficking. Mr. Grimaldi has frequently been able to suppress evidence from being introduced at trial, and this has led to numerous dismissals and acquittals. On other occasions, he has negotiated favorable plea agreements with the prosecution. Mr. Grimaldi’s successful track record has led to a significant amount of recognition from his colleagues, including a 10.0 “Superb” peer-review rating through Avvo.

    Mr. Grimaldi has often been invited to deliver presentations to groups of fellow attorneys on topics related to his practice area. In 2013, he expanded his knowledge through his participation in the National Criminal Defense College Trial Practice Institute. A member of the Massachusetts Association of Criminal Defense Lawyers, he is admitted to practice in Massachusetts and before the U.S. District Court for the District of Massachusetts.
