Sarah E. Warner

Sarah E. Warner

Lawrence, Kansas Attorney

Sarah has the unique experience of having worked in the highest courts of two different states: Kansas and Michigan. Most significantly, immediately after graduating from law school, Sarah served as the judicial clerk for the Honorable Robert E. Davis of the Kansas Supreme Court.  During her 3 ½ years at the Court, Sarah researched and made recommendations to the justices on more than 100 pending cases, ranging in subject matter from first-degree murder to eminent domain to complex civil litigation and class actions. When Justice Davis became Chief Justice of the Kansas Judicial Branch in January 2009, Sarah was given the additional responsibility of coordinating the efforts of the judicial clerks in all Kansas Supreme Court chambers and assisting with the Chief Justice's interactions with the legislative and executive branches. The skills Sarah developed during her time at the Court prove invaluable in her everyday practice and representation of clients.

Sarah joined Thompson Warner, P.A. in November 2009, but she is no stranger to the firm, having worked as a law clerk with us before she attended law school. Sarah's practice focuses primarily on resolving state and federal constitutional claims; contract disputes, including questions of insurance coverage and allegations of bad faith; disputes relating to eminent domain, land use, and real estate; and bodily injury claims. Sarah has developed a specialty in appellate advocacy, involving not only successfully briefing and litigating appeals, but also conducting practice sessions for other attorneys preparing to argue cases before the Kansas and federal appellate courts.

While in law school, Sarah was an editor on the Ave Maria Law Review from 2004 to 2006.  Upon graduation, Sarah received the Mary Queen of Lawyers Award, which is awarded by the faculty to the most outstanding law school graduate based on grades, coursework, and personal character.

For the past several years, Sarah has taught Conflict of Laws as an adjunct professor at Washburn University School of Law in Topeka. The course, which is increasingly critical in our interconnected society, examines the legal and policy considerations that arise in cases where more than one jurisdiction has an interest in ongoing litigation (whether it be multiple states or a conflict between federal and state interests), how these considerations affect a court’s power to hear the case, and when and how judgments from one state can be recognized in another.  Sarah also serves as a member of the University of Kansas Honors Program Alumni Advisory Board and a cantor and member of the folk group at Holy Trinity Catholic Church in Lenexa.
