About Thomas L.
Thomas L. Gallivan earned his law degree from St. John’s University School of Law in 2004 after completing a B.A. in economics at Loyola College in 2001. He moved into legal work soon after graduating law school and built a career largely in New York. His education paired a small-college undergraduate background with a metropolitan law school, giving him both regional ties and urban courtroom exposure.
He began his legal career in 2004 at Duffy & Duffy, Esqs., where he worked as a lawyer in the firm’s early ranks. The following year he joined Mendes & Mount LLP and then moved to Kaufman Borgeest & Ryan LLP in 2006. Those early years put him in established firms and exposed him to a range of civil litigation matters and firm practices.
In 2008 he opened the Law Offices of Thomas L. Gallivan, PLLC, operating as the principal lawyer. That step marked a shift to private practice and client-facing work under his own banner. In 2018 he returned to Duffy & Duffy in an of counsel capacity at Duffy & Duffy, PLLC, while continuing his own practice. The timeline suggests a blend of firm experience and independent practice, and both roles appear on his public record.
Gallivan is admitted to practice in New York. He maintains memberships in several professional groups, including the Long Term Care Community Coalition, the New York State Trial Academy and the Westchester County Bar Association. Those associations indicate ongoing engagement with local bar activities and specialized professional networks tied to trial practice and long-term care issues.
Colleagues and clients have encountered him in courtrooms and in counseling settings. His career path moved from associate positions at New York firms to building a private practice and then adding an of counsel role at a firm where he previously worked. That arc reflects a common pattern: early training in larger firms, followed by independent practice and selective collaboration with prior employers.
He is based in Westchester County and has maintained practice contacts across the region. Day-to-day work has included civil litigation and matters that touch on long-term care policy and regulation, consistent with his association memberships. He remains active in the local bar and in professional training programs that prepare attorneys for trial work.
Today he practices from the Law Offices of Thomas L. Gallivan, PLLC and serves of counsel to Duffy & Duffy, PLLC, focusing on civil litigation and issues related to long-term care and trial practice.
