Marian T. Ryan has been appointed to be the next Middlesex District Attorney by Governor Deval Patrick.

“I am humbled by the responsibility which the Governor has entrusted to me,” said Ryan.  “I am thrilled to be leading the Office where I have spent my entire professional career and I look forward to continuing its long tradition of excellence.”  

Ryan has worked as a Middlesex County assistant district attorney for more than thirty years.  She has risen through the ranks of the office, serving under 5 different District Attorneys, as a District Court supervisor, a Superior Court trial team captain, and as the Chief of the Domestic Violence and Elder/Disabled Units.  Most recently, she has served as General Counsel and Chief of the Elder and Disabled Unit under former District Attorney Gerry Leone.

Throughout her career, she has prosecuted hundreds of cases, including that of Walter Emery, a case which had remained unsolved for more than 20 years until he was convicted in 2007 for the murder of a mother of three. She has also briefed and argued more than 40 cases in the Appeals Court and the Supreme Judicial Court. 

Ryan has been a passionate advocate for the most vulnerable victims, including the elderly and developmentally disabled people who have been taken advantage of financially and physically abused. 

She has also been actively engaged in the Office’s outreach and training efforts, and has developed and led programs on work place violence prevention and school safety.

Ryan has been an adjunct professor at Emmanuel College and Wentworth Institute, and is currently teaching at Lasell College.

She is a graduate of Boston College Law School and a past recipient of the school’s David S. Nelson Public Service Award.  She received her undergraduate degree from Emmanuel College.

Ryan lives in Belmont with her husband, and has 2 children.
