About Joseph Gregory
Joseph Gregory Hannigan earned his undergraduate degree from the University of Notre Dame before turning to law at American University, where he received his J.D. The combination of a liberal arts background and professional legal study shaped a practical approach to problem solving. He left law school prepared for the procedural and analytical work that characterizes modern practice.
At Notre Dame he developed an interest in civic and public affairs. At American University he studied coursework that emphasized legal research and advocacy. Those years established the technical foundation he would use in practice. Faculty and peers recall a student who favored careful analysis over rhetorical flourish. That tendency shows in the steady progression of his legal qualifications.
After law school Hannigan gained admission to practice in both Maryland and Pennsylvania. He maintains licensure in those jurisdictions and conducts his legal work across state lines. His admissions allow him to appear before state courts and work directly with clients in two distinct legal environments. That dual admission reflects a willingness to handle matters that cross borders within the Mid-Atlantic region.
Hannigan’s work has involved the routine tasks of legal practice: counseling clients, preparing filings, and engaging in negotiation and dispute resolution. He applies the doctrinal training from law school to contemporary client problems. Colleagues describe his approach as methodical and unhurried. He prefers building legal positions that are defensible and clear rather than relying on persuasive flourish.
Outside of casework, Hannigan remains connected to the legal community in both states. He participates in continuing legal education and keeps abreast of statutory changes that affect his clients. Keeping current has been a consistent part of his professional routine since his admission to the bars.
Over time Hannigan has solidified a practice that draws on his academic background and his dual-state admission. He practices law in Maryland and Pennsylvania, representing individuals and entities across those jurisdictions. He currently focuses his practice on serving clients in Maryland and Pennsylvania.
