Boston Criminal Defense Attorney Greg L. Johnson

In January 2011, Attorney Yannetti handpicked Attorney Greg L. Johnson to join him at the Yannetti Criminal Defense Law Firm after the two attorneys had battled each other in a highly contested and lengthy gun case in the Lawrence District Court. At the time, Greg was working as a prosecutor for the Essex County District Attorney’s Office. Attorney Yannetti viewed first-hand the skill Greg exhibited, as well as the respect he commanded from judges and court personnel. Attorney Yannetti was so impressed that he offered Greg an associate’s position in the firm.

Attorney Greg L. Johnson has established himself as a true rising star in the criminal-defense bar. In both 2020 and 2021 Attorney Johnson was named to Massachusetts Super Lawyers, a selection process limited to those who have attained a high degree of peer recognition and professional achievement.  Between 2013 – 2018 he was nominated as a “Rising Star” by Super Lawyers six consecutive years. Only 2.5% of eligible attorneys nationwide are honored with the “Rising Star” distinction.   This accolade further cemented Attorney Johnson’s growing reputation for top-level representation in criminal courts throughout Massachusetts and New Hampshire.

During his career as an assistant district attorney, Greg L. Johnson gained invaluable trial experience, which included his representation of the Commonwealth as lead counsel in approximately fifty jury trials. In 2008, he was selected to work under the Project Safe Neighborhood Grant funded by the U.S. Attorney’s Office. His responsibilities in that position included prosecuting all firearms and gang-related offenses in the City of Lawrence. In that role, Attorney Johnson handled a wide variety of serious felony cases, including shootings, assaults by means of dangerous weapons, narcotics distribution and firearms cases. In 2008, the Massachusetts District Attorney’s Association selected Greg to receive the Spotlight Award which is issued annually to prosecutors in recognition of outstanding service, spirit, and professionalism.

Attorney Johnson was promoted in January of 2010 to the position of Supervising ADA at the Lawrence District Court, one of the five busiest courts in the Commonwealth. He was responsible for the training and supervision of ten Assistant District Attorneys. Before leaving the District Attorney’s Office, Attorney Johnson presented approximately ten serious felony cases to the Grand Jury and handled those matters in the Essex County Superior Court.

Attorney Greg L. Johnson’s extensive experience and substantial growth as a trial lawyer are integral components of his success at the Yannetti Criminal Defense Law Firm. His ability to assess, analyze, and exploit the weaknesses in the prosecutor’s cases against his clients is a tool that informs his daily approach to our cases inside and outside the courtroom.
