About James K.
James K. Theisen earned his law degree from Southern Illinois University Carbondale in 2002. He completed the J.D. program there at a time when the legal market was shifting and new paths were opening for litigators and transactional lawyers alike. He is licensed to practice in Illinois and has spent his professional life working within the state.
Early in his career Theisen joined the staff at Hupy and Abraham, serving as an associate lawyer in 2014. His time there placed him in a firm environment known for high-volume client work and trial practice, where associates often handle case preparation, discovery and courtroom appearances. That role gave him regular exposure to litigation procedures and firm operations.
Beyond day-to-day practice, Theisen has maintained ties to the organized bar. He holds current memberships in the Illinois State Bar Association and the Winnebago County Bar Association. Those affiliations have kept him connected to continuing legal education and local professional networks. They also reflect a practice rooted in the state and its legal community.
Throughout his career Theisen has practiced in several Illinois locations. His professional footprint includes offices in Gurnee, Bloomington and Rockford. Working from multiple offices has required balancing client meetings, courtroom schedules and case management across different venues. It has also meant adapting to the varying needs of clients in suburban and regional courts.
Colleagues describe Theisen as steady in litigation settings and attentive in client matters. He has handled tasks common to trial teams: drafting pleadings, preparing witnesses, and coordinating with experts. Those responsibilities have shaped a pragmatic approach to casework. He prefers clear lines of communication and careful preparation before hearings and trials.
For clients and other attorneys, Theisen offers experience grounded in Illinois practice and the procedural demands of civil litigation. He remains active in state and local bar groups and continues to work from offices in Gurnee, Bloomington and Rockford. His current practice focuses on serving Illinois clients across those regional offices.
