About Jason
Jason Hahn built his legal foundation in the Midwest. He earned a Bachelor of Arts in political science from Illinois State University and later graduated from the University of Wisconsin Law School with a J.D. His academic path set him up for work in both state and federal courts.
He began practicing in the years that followed law school and is recorded as working at Hupy & Abraham S.C. in 2010. Details of his responsibilities there are not listed here, but the position placed him at a firm known for plaintiff-side litigation. Over time he moved toward establishing his own practice.
In 2025 he became the owner of Hahn Law Office, LLC. That move formalized a shift from working within a larger firm structure to running an independent legal enterprise. As owner he handles the administrative and case-related responsibilities that come with managing a small firm.
Hahn is admitted to practice in Wisconsin and is also admitted to the United States Court of Appeals for the Seventh Circuit. Those credentials allow him to appear in state trial courts and to participate in federal appellate matters that arise within the Seventh Circuit jurisdiction. He has maintained an active practice across these venues.
Colleagues describe him as methodical in preparing filings and attentive to procedural requirements. He takes a pragmatic approach to scheduling and deadlines. Clients and opposing counsel have noted his steadiness in court settings and during appellate briefing. He presents arguments on paper and orally with an emphasis on clarity and adherence to applicable rules.
Outside the courtroom he oversees operations at Hahn Law Office, LLC. Running the office requires balancing client work, case management and the business aspects of a law practice. He organizes case files, supervises any staff or contractors he brings on, and coordinates filings for matters in both state and federal forums.
His career shows a progression from law school through firm experience to founding his own firm. That arc reflects a move toward greater control over caseload and practice management. His current practice focuses on matters in Wisconsin and before the Seventh Circuit.
