About Kevin S.
Kevin S. Sullivan built a steady legal career from a grounding in economics and a law degree earned in the mid-1980s. He graduated from the University of Vermont with a B.S. in Economics in 1982, then received his J.D. from Suffolk University Law School in 1985. Those academic years set the stage for a practice shaped by courtroom work and client counseling.
He began his legal career in 1985 at Callan, Sullivan & Burke, P.C., where he served in associate and partner capacities. The early years there gave him regular courtroom exposure and experience handling a range of matters in state courts. Colleagues from that period recall a steady approach to case preparation and an attention to procedural detail.
In 1998 he became a partner at Sullivan & Sullivan, LLP. That move marked a shift into a leadership role and a greater hand in managing cases and mentoring younger lawyers. His time in that partnership encompassed trial work and the operational tasks that come with running a mid-sized practice.
In 2003 he launched his own firm, Law Offices of Kevin S. Sullivan, LLC, as manager and sole practitioner. Running a one-person firm requires handling everything from client intake to litigation strategy and billing. Over the years he has maintained an independent practice while remaining active in bar groups across Massachusetts.
Sullivan is admitted to practice in Massachusetts and is admitted to the bar of the U.S. Supreme Court. He maintains memberships in the Massachusetts Bar Association, the Massachusetts Bar Foundation, the Massachusetts Association of Trial Lawyers, and the Greater Lowell Bar Association. Those affiliations reflect sustained ties to the state’s legal community and to organizations that provide continuing education and networking for litigators.
His career has threaded together courtroom practice, firm leadership, and independent practice. He has moved through the roles of associate, partner, and sole practitioner while keeping an active presence in local bar activities. The result is a practice shaped by long-term familiarity with Massachusetts courts and procedures.
As of 2026 he continues to operate the Law Offices of Kevin S. Sullivan, LLC and handles matters arising in Massachusetts, and he remains admitted to practice before the U.S. Supreme Court. His current practice focuses on litigation and court work in Massachusetts and related federal filings.
