John D. Tongier


John Tongier is the principal Member of John D. Tongier, LLC. He is licensed and practices law in both Kansas and Missouri, representing plaintiffs in personal injury litigation, with an emphasis in medical cases and cases focusing on medical/nursing care issues. He also serves as a Mediator in all forms of personal injury cases in both states.

Born in 1957, John grew up in Coffeyville, Kansas. He received his undergraduate degree from the University of Kansas in 1979 and his law degree in 1982 from Washburn University School of Law in Topeka. Early on, John knew that representing injured plaintiffs was the area of the law that he found most fulfilling, however, his path to becoming a full-time personal injury attorney was less than direct. 

Early in his career, John worked as a litigator for a defense firm in Kansas City, Kansas as an associate, later becoming a partner with the firm. During this time, John's litigation practice emphasis was on defending medical claims. While primarily handling defense files, John was still drawn to representing injured persons and settled his first case for the family of an injured child in excess of $1 million shortly after associating with the firm. What always struck John was the realization that being able to help an injured person or their family put their lives back together after an accident or injury was far more gratifying than saving an insurance company a few thousand dollars when defending a claim. That sense of fulfillment in representing individual plaintiffs and their families became evermore clear for him over the years that followed. 

In 2001, John joined with Dan Strausbaugh to form Strausbaugh & Tongier, L.L.C., where they maintained their practice through 2014. In 2015, John formed John D. Tongier, LLC continuing to devote the vast majority of his practice to representing injured plaintiffs, with a case load equally divided between Kansas and Missouri courts. He is a member of the Kansas Bar Association, having served three years on the KBA's Litigation Section Committee. He is also a long-time member of the Kansas Association for Justice. Martindale-Hubbell, the legal directory that rates attorneys based on surveys of the legal community, gave John an “AV rating” – the highest rating for legal ability and integrity.

​John's areas of expertise include medical negligence, wrongful death, birth trauma and surgical injuries. During his career, he has given numerous CLE lectures to fellow lawyers as well as CME presentations to doctors and nurses on malpractice litigation issues, nursing documentation, nursing home litigation and participated in several mock trials for various health care providers. In addition to medical cases, John has also represented numerous plaintiffs and their families injured in serious motor vehicle accidents.

The most significant growth area of John’s law practice is his service as a Mediator for other attorneys and their clients. With his past experience of representing both plaintiffs and defendants, John has enjoyed sustained success in helping litigants resolve their disputes short of trial, saving all parties enormous time, stress and money. John’s litigation and mediation skills have also served him well in maintaining a successful Johnson County, Kansas divorce practice. 

A unique area of John's litigation practice is in will/trust challenges. In these disputes, his experience in examining medical records gives him a valuable perspective in determining whether a person, usually advanced in years, had the necessary mental capacity to make a recent change to their estate plan. These cases can be the subject of vigorous, protracted litigation, particularly among family members or a late-in-life spouse.

John is married to wife, Lisa, and he has three children - Hank, Claire and Will. He enjoys hiking, camping (even a little backpacking) and playing tennis.
