Lauren Horsman was born and raised in Chillicothe, Missouri. She graduated from the University of Missouri-Columbia School of Journalism, cum laude, in 2005 and graduated from the University of Missouri-Kansas City School of Law in 2008. In law school, Lauren was selected to the Order of the Barristers and Managing Editor of The Urban Lawyer. While in law school, Lauren was an intern at the Johnson County, Kansas District Attorney’s Office, where she prosecuted domestic violence cases and conducted numerous bench trials, including her first jury trial.

Lauren began her legal career as a judicial clerk for both the Missouri Court of Appeals and Missouri Supreme Court before joining the Missouri Attorney General’s Office. As an Assistant Attorney General, Lauren defended state agencies in civil rights litigation, employment matters, and personal injury lawsuits. During her tenure at the Missouri Attorney General’s Office, Lauren successfully conducted several jury trials in both state and federal court as well as argued appellate matters in front of the United States Court of Appeals for the Eighth Circuit and the Missouri Court of Appeals. Prior to joining Chapman and Cowherd, P.C., Lauren practiced law at a large international law firm, where she was a member of the Commercial Litigation team and participated in litigation in both Missouri and Kansas state and federal courts.

Lauren’s practice includes all aspects of the civil litigation process, including case strategy, motions practice, depositions, trials, and appeals. Lauren has a wide range of experience representing clients in dissolutions, paternity and custody actions, contract disputes, negligence actions, general business matters, drafting of wills and estates, and land disputes. In 2019, Lauren was appointed the Mercer County, Missouri Prosecuting Attorney by Governor Parson, a duty she discharges in addition to her civil law practice. Lauren provides representation for all of her clients’ legal needs, with a practice primarily focused on civil litigation, family law, and estate planning.

Lauren is admitted to practice in Missouri, Kansas, United States District Courts in Missouri and Kansas, and the Eight Circuit. Lauren is an alumna of the Missouri Bar Leadership Academy and The Missouri Bar Young Lawyers Section. Lauren is a member of the Chillicothe Area Chamber of Commerce Board of Directors, Chillicothe R-2 Board of Education, Tria Sorosis, and member of the United Methodist Church (along with her husband Ryan and their two daughters).
