About Sean P.
Sean P. Sullivan studied political science at the University of Iowa before turning to law. He earned his J.D. from Western Michigan Law School in 2009. Those formative years set a clear path: courtroom procedure, case strategy and state-federal practice.
He began building his practice in Illinois. By 2015 he was a senior associate at the Law Offices of Laura Urbik Kern, LLC, and in 2017 he held a senior associate role at O’Flaherty Law. Those positions put him on complex matters that required court appearances and detailed motion work. Colleagues describe him as steady under pressure and attentive to the rhythm of litigation.
Sullivan is admitted to practice in Illinois and has federal court admissions in the Northern and Central Districts of Illinois. That combination allows him to carry cases between state and federal forums, draft federal pleadings and appear on calendar calls in multiple districts. He draws on courtroom experience when preparing cases for hearings and trial.
Professional membership has been part of his career rhythm. He holds membership in the DuPage County Bar Association, where he engages with local bar activities and professional development opportunities. The county bar connection also keeps him plugged into the legal community in the suburbs west of Chicago.
His work history spans small firm practice and larger defense-oriented environments. At the Law Offices of Laura Urbik Kern he handled a range of matters that required meticulous client communication and tight calendaring. At O’Flaherty Law he worked on matters that involved coordinating discovery and managing witness preparation. Those roles demanded practical litigation skills more than theoretical approaches.
In recent years Sullivan has been practicing at SBK Law Group, maintaining ties to the western suburbs through offices in Downers Grove and Naperville. He brings a courtroom-ready approach to case preparation and a familiarity with local court procedures. He is pragmatic in advising clients about procedural options and timing. He balances written advocacy with oral argument and prepares matters to move when a court schedule requires it.
He continues to work in Illinois courts and in the federal districts where he is admitted. He currently practices at SBK Law Group from the Downers Grove and Naperville offices, where his work centers on litigation in Illinois state and federal courts.
