Prior to joining the firm, Eugene served as Corporation Counsel for the City of Boston where he was the chief legal officer for former Boston Mayor Martin Walsh, who was appointed President Biden’s Secretary of Labor in 2021. From 2014 to early 2021, Eugene was responsible for managing an office of 60 attorneys, paralegals and administrative staff and serving as a senior cabinet advisor to the Mayor, providing high-quality and effective legal advice and representation on all legal matters involving the Mayor, Boston City Council, all City Departments and Boards & Commissions. 

Before working for the City of Boston, Eugene served in the Massachusetts House of Representatives for seventeen years. He began practicing law in 1994 and was elected to the Massachusetts Legislature in 1996, where he served on the Education Committee and as Vice-Chairman of the Banks and Banking Committee before being appointed to serve as the House Judiciary Chair in 2002.

During his twelve-year tenure at the helm of the Judiciary Committee, Eugene was responsible for the drafting, implementation, review and strategizing associated with the largest number of legislative proposals before the Massachusetts Legislature. For his public service efforts, Eugene was honored for excellence by the Massachusetts Bar Association, Boston Bar Association, Massachusetts Academy of Trial Attorneys, Massachusetts Legal Assistance, Children's Trust Fund, Massachusetts Society for Prevention of Cruelty to Animals, and the Animal Rescue League among other organizations.

In addition to his legislative duties, Eugene served as a member of the House Leadership Team for more than a decade and under three successive Speakers of the House and played a pivotal role in advising, advocating for and polling the 160-member House on a wide variety of legislative issues.

Notably, Eugene spearheaded the sister city agreement between Boston and Belfast, Northern Ireland which results in annual exchanges and visits by elected officials and members of the business community. He also organized the Friendship Four Hockey Tournament that annually brings four American university teams to compete in Belfast for the BelPot Trophy during the Thanksgiving holiday. The tournament has been acknowledged as crucial in continuing initiatives to support the peace process there.
