Ryan W. Horsman

Ryan Horsman was born in St. Joseph, Missouri and raised in Platte City, Missouri. He is a 2004 graduate of the University of Missouri-Columbia, where he earned a B.S. in Political Science, and a 2007 graduate of the University of Missouri-Kansas City, where he was a member of the AAJ national trial team and was awarded the Dillingham Public Service Award.

Upon graduation, Ryan began his legal career as an associate at the large national law firm of Shughart, Thomson & Kilroy, P.C. and its successor law firm, Polsinelli, PC. While at Polsinelli, Ryan was a member of the business litigation practice group, where he was involved in several significant state and federal lawsuits and was also charged with representing two of the law firm’s major clients in workers’ compensation proceedings. In his time with Polsinelli, Ryan was able to gain valuable insight into the litigation process from the perspective of large corporations and insurance companies.

Prior to joining the Chapman & Cowherd, P.C., Ryan served the Jackson County, Missouri Prosecutor’s Office in the Special Victims’ Unit (SVU) in Downtown Kansas City and in the Independence Drug Unit. Ryan served as lead counsel on numerous cases including: murder, rape, sodomy, statutory rape, statutory sodomy, child molestation, child abuse, domestic assault, assault, unlawful use of a weapon, burglary, robbery, armed criminal action, possession of a controlled substance, distribution of a controlled substance and driving while intoxicated. As a result of his work in Jackson County, Ryan was honored to receive recognition as the 2017 “Prosecutor of the Year” from the Professional Fire and Fraud Investigator Association.

In November of 2016, then Governor Jay Nixon appointed Ryan to serve as Mercer County Prosecuting Attorney. In his private practice at Chapman & Cowherd, P.C., Ryan uses his extensive litigation experience to represent clients in civil litigation, family law and workers’ compensation claims. Ryan has successfully conducted jury trials and administrative hearings throughout Missouri and he uses that experience to achieve the best results possible for his clients.

Ryan, his wife Lauren, and their two young daughters are members of the United Methodist Church of Chillicothe. In his free time, Ryan enjoys coaching youth sports, playing golf, taking family walks and cheering on the Mizzou Tigers, Kansas City Royals and Kansas City Chiefs.
