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.
