Keenan is licensed to practice law in all Massachusetts State Courts, the Federal District Court for the District of Massachusetts, the Federal First Circuit Court of Appeals, and the United States Supreme Court.
During his time in law school, Keenan became actively involved in local governance. He was appointed as the Chairperson of the Quincy Mayor’s Commission on Handicapped Affairs and later served on the Quincy Zoning Board of Appeals for seven years. In 1997, he was appointed Executive Secretary under Quincy Mayor Jim Sheets, where he managed the city's municipal departments and oversaw the budget preparation and financial reviews. In 2001, he transitioned to the role of Executive Director of the Norfolk County Retirement System, managing a public pension system that serves approximately 10,000 active and retired members with significant assets.
