Professional Biography

With over thirty years of litigation experience, former Massachusetts Attorney General Thomas F. Reilly is one of the country’s preeminent trial attorneys. Tom joins Cooley Manion Jones after twenty-five years in public service including two terms as District Attorney of Middlesex County and Attorney General of Massachusetts. As Attorney General, Tom assembled, trained, and led a dynamic group of over 300 lawyers with jurisdiction over and expertise in virtually every major substantive area of litigation including: commerce, banking and finance, eminent domain and land use, insurance, product liability, criminal, non-profit, consumer, labor, tax, and environmental. Martha Coakley, the current Attorney General of Massachusetts, Gerry Leone, the current District Attorney of Middlesex County, and Carmen Ortiz, United States Attorney for the District of Massachusetts, all worked with and were mentored by Tom.

Throughout his tenure as District Attorney and Attorney General, Tom consistently proved himself an able and fearless advocate. Tom garnered national attention when he personally led the investigation into the corruption surrounding the Central Artery “Big Dig” construction project, the largest public works project in American history. He was also in the national spotlight as he spearheaded an eighteen month civil and criminal investigation that dealt with the sexual abuse of children in the Boston Archdiocese. This complex investigation documented the tragedy of over 700 instances of child abuse, resulted in several convictions and ultimately led to the adoption of new policies and procedures for the future protection of children. Tom led the successful challenge before the United States Supreme Court, where he challenged the United States Environmental Protection Agency's failure to regulate carbon dioxide in a seminal environmental regulation case.

At CMJ, Tom applies his extensive knowledge, experience, and expertise to lead the Government Investigations and Defense practice group. Tom’s diverse client base includes global, regional and local clients from a variety of industries including manufacturing, financial services, higher education, health care and construction. These clients turn to Tom and his team for trusted advice, fierce advocacy and strategic solutions when facing investigation by federal, state law enforcement and regulatory agencies in matters involving alleged anti-trust violations, corporate fraud and bribery, securities violations, consumer protection violations, security breaches and other alleged white collar offenses.

Tom received his law degree from Boston College Law School. He is married to Ruth Reilly and they have three grown children: Leslie, Meaghan and Kyle.
