Greg's entire legal career has been with the Norfolk District Attorney's Office. He began as an intern in 1996 in William Delahunt's office, then was hired in March 2001 by William R. Keating.

In the 25 years since, he has served as a line ADA, Chief of the District Courts, Chief of the Motor Vehicle Homicide Team, Chief of the Financial Crime Unit, and, finally, Chief Trial Counsel. In 2024, the 11 sitting District Attorneys voted Greg Prosecutor of the Year.

He has taken on some of the most complicated matters, including the Puppy Doe case, in which he was the first lawyer in Massachusetts history to introduce canine DNA evidence. As lead prosecutor in the Commonwealth v. Emanuel Lopes case, Greg secured murder convictions for the man who killed Weymouth Police Sergeant Michael Chesna and civilian witness Vera Adams. Most recently, in the Ana Walshe case, Greg became the first person in over 100 years to obtain a first-degree murder conviction in a matter where there was no body of the victim. He implemented and developed the Drug and Veterans Courts, providing support to those in need of treatment and recovery.

Greg was inspired to live a life of public service by his parents. His mom, Judy, was raised in Medfield and moved to Walpole to raise her family. She was an area teacher, a local realtor, and regularly volunteered in her community of Walpole. Greg’s father, Jack, was raised in Norwood. Like Greg, he attended Boston College for undergrad and law school and began his career in the Norfolk District Attorney's Office under George Burke. Jack then became a founding partner of Connor and Hilliard in Walpole. Returning to public service, Jack was a judge in District and Superior Courts before retiring in 2014. Greg learned from his parents how important it is to give back and improve your community.

Greg firmly believes that an effective District Attorney must reach out beyond the courtroom. Working with local police, schools, social service providers, and other local groups to address dangerous behavior before it becomes criminal is fundamental to maintaining communities that are safe, strong, and vibrant.=

The Norfolk County District Attorney’s Office has done ground-breaking work over the years to protect victims and save lives through prevention programs targeting substance abuse and resulting overdose. Greg is eager to build upon those successful programs and lead the Office into a new era.

Greg is eager to establish an Emerging Adults Court to help 18-21-year-olds charged with non-violent offenses avoid a criminal conviction. He plans to create a dedicated team of attorneys and investigators to bring closure to unresolved or “cold” cases. He wants to expand community outreach programs to further protect at-risk seniors from falling victim to fraud and abuse. After his experience prosecuting the “Puppy Doe” matter, Greg is seeking to establish a team to fight animal abuse cases. Greg also plans to write, file, and champion true hate crime legislation that would make hate crimes a felony.

In 2002, Greg was named the District Court prosecutor by William Keating. 

In 2020, when Covid prevented jury trials from occurring, Greg helped found the Conviction Integrity Committee to reverse past miscarriages of justice.

In 2024, the 11 District Attorneys from across the Commonwealth named Greg Prosecutor of the Year.

Greg is a former President of the Quincy Bar Association, and a longtime member of the Norfolk County Bench Bar Committee and the Norfolk County Bar Association. 

He is a frequent lecturer at Boston College, the Massachusetts District Attorney Association, Massachusetts Continuing Legal Education, and the Social Law Library. Greg has also been a contributing author on legal texts for MCLE and MDAA.
