Ann Barron

Attorney in Edwardsville, IL

Early in her practice, a mentor on the Illinois Supreme Court required Ann Barron to learn by doing, a philosophy that continues to guide her to never turn away from the toughest challenges. Those experiences allowed her to hone her legal writing skills and knowledge of Illinois law and procedure, giving her a unique perspective on litigation from document preservation, to setting reserves, to keeping those in the C-suite informed. Today Ann co-chairs the firm's Appellate practice group and concentrates her practice on civil litigation, including environmental and business-related disputes, medical malpractice litigation, and personal injury defense.

In over 15 years of practice in southern Illinois and Missouri, Ann has handled cases in Illinois county courts from Springfield south, all Illinois appellate courts, and the Seventh Circuit, appreciating each court's unique vibe and interesting history. She understands that it is essential to know the community where you are practicing, believing that a lawyer's intellectual curiosity allows them to learn the law and statutory scheme about any practice area and then apply that to the facts of the case and the jurisdiction where the case is pending. This approach has led to Ann's exceptional competence in all stages of litigation, from suit filing through a petition for writ of certiorari to the United States Supreme Court.

Ann enjoys spending time with her family outside the office, traveling to Yellowstone, attending Broadway and the St. Louis Speaker Series, or watching the Edwardsville High School Marching Band competitions.  She values their time together. An Illini alum and proud supporter of the orange and blue, you will know when Ann is in the office; look for the orange Jeep. Ann stays active with her alma mater continuing to serve on various boards and panels.
