Leininger Law Offices is a criminal defense law firm in Overland Park, Kansas, serving Johnson, Douglas, Wyandotte, Leavenworth and Miami Counties and handling cases throughout Eastern Kansas. Attorney Brian Leininger has been handling DUI cases every working day since 1991 and almost certainly has more DUI training than the officer who arrested you. My years of experience began as an Assistant District Attorney and later City Prosecutor. Additionally, I spent nearly five years as General Legal Counsel to the Kansas Highway Patrol. I used to teach police officers how to make DUI and drug arrests. Now when I teach at seminars the topic is DUI defense and the audience is made up of other lawyers.
