Home Attorneys Kason Kimberley

Since entering the practice of law in 2014, Kason has appeared in state and federal courts in Texas, New Mexico, Louisiana, Oklahoma, Arkansas, Utah, New York, Ohio, Arizona, and Georgia on behalf of clients in serious injury, catastrophic injury, and products liability cases.

A native of Whitehouse, Texas, Kason earned his bachelor’s degree from the University of Chicago in 2007, with general honors. He graduated cum laude in 2014 from the SMU Dedman School of Law in Dallas, TX where he was a Rosemary and Tom Medders Scholar, interned for the Hon. Terry R. Means of the United States District Court for the Northern District of Texas, and was a member of several invitation-only moot court teams including the Jessup International Moot Court Competition. Kason tried his first case in Dallas County as a third-year law student in the SMU Criminal Justice Clinic, and won.

Before law school, Kason served as the founding Executive Director of the Dallas Urban Debate Alliance, a community education non-profit dedicated to building a rigorous debate program for urban public school students in Dallas. He received the organization’s Distinguished Service Award in 2010 and actively volunteers with the organization.

Kason is an Army veteran who approaches every case, and every client, with an ethos of integrity and selfless service. In addition to his work at the Lenahan Law Firm, Kason continues to serve as a Civil Affairs Officer in the US Army Reserve, holding the rank of Major. Decorations include the Meritorious Service Medal, Army Commendation with 2 oak leaf clusters, Global War on Terror Expeditionary Medal, Reserve Component Achievement Medal, a “Commandant’s List” designation from the US Army John F. Kennedy Special Warfare Center and School, and the Colonel Decius Wadsworth Award of Scholarship, presented on the occasion of graduating ranked first in his class from the US Army Basic Officer Leaders Course.

Kason’s proudest achievements as an attorney are not measured in dollars and cents but in the actual changes made to improve public safety. In 2016, for instance, a state and federal investigation into the death of one of Kason’s clients led to a public reprimand and a suspension and a suspension of federal funding for a Defendant. In 2018, a defendant rewrote its procedures as a result of what happened to Kason’s client and, in 2019, another defendant rewrote their policies to keep what happened to Kason’s client from ever happening again.

When not at the firm or fulfilling military responsibilities, Kason spends his time with his three young daughters and his wife, a public high school teacher.
