About Thomas R
Thomas R Siegel has spent much of his career in courtrooms rather than boardrooms. He reads a docket the way some people read a map. Crisp and exact, the calendar tells the story of a lawyer who built a practice around trial work and institutional leadership. He earned his B.A. from Monmouth College in 1995 and his J.D. from Northern Illinois University in 2002.
Early in his career he took on roles that tied him to public defense and to local bar work. He served as secretary-treasurer of the Warren County Bar Association in 2003 and rose to its presidency in 2011. Those posts gave him steady contact with the community bench and bar. They also framed a pattern in which courtroom duties and professional governance moved in parallel.
Siegel’s involvement with the Illinois Public Defender Association is one of the clearer through-lines in his professional life. He served on the Council of Chief Defenders and acted as its vice president in 2013. The following year he was second vice president of the statewide Illinois Public Defender Association. Alongside those roles he joined the board of West Central Illinois Community Services’ Head Start program in 2014, a post that connected his legal work to local social services and family-focused programs.
Admitted to practice in both Illinois and Iowa, Siegel is also authorized to appear before the Seventh Circuit and the U.S. Supreme Court. That combination of state and federal admissions reflects steady courtroom practice, including appellate filings and federal matters that grew out of trial work. He has kept a steady presence in the networks that serve public defenders and county bar associations rather than pursuing a path centered on private-firm marketing or academic roles.
Colleagues describe him as deliberate and practical in how he approaches a case. He moves methodically through investigations and hearings, and he has taken leadership posts that involve administration as much as advocacy. That mix has shaped a professional identity rooted in courtroom practice, bar governance and community service.
He currently practices public defense and continues to handle trial-level cases while remaining active in professional associations and community boards.
