Kate Rumsey is special counsel in the Governmental Practice in the firm's Dallas office. Kate is a former federal prosecutor and experienced trial lawyer and litigator.

Areas of Practice

As the daughter of a pharmacist and small business owner, Kate understands how a government investigation can impact a business as well as emotionally impact business owners. Kate uses that understanding of the healthcare industry as well as her experience as a federal prosecutor to help clients navigate high-stakes investigations and litigation. 

As a federal prosecutor, Kate was responsible for investigating fraud, public corruption, cyber threats, identity theft, and overprescribing opioids. She started her prosecutorial career on the DOJ’s health care strike force team and therefore has specific experience in health care fraud and parallel investigations. Kate has worked with many federal and local agencies, including the Federal Bureau of Investigation, Drug Enforcement Administration, U.S. Department of Health and Human Services, U.S. Food and Drug Administration, U.S. Immigration and Customs Enforcement, Department of Defense, Department of Agriculture, Department of State, and Secret Service, among many others. For her work as a prosecutor, Kate has received several awards, including a Special Commendation from the U.S. Attorney General. 

Prior to being a prosecutor, Kate served as a federal law clerk to Judge Barbara M.G. Lynn in the Northern District of Texas and was a senior associate in the litigation and white collar groups of a global law firm. 

Kate has also served as a JAG officer in the U.S. Air Force Reserves, where she has participated in courts martial and contested discharge boards. She won an award for public speaking while at Officer Training School and was named JAG reservist of the year in the Second Air Force.

Between private and government practice, Kate has successfully tried numerous cases to a jury and has extensive first-chair trial experience. Kate has also regularly handled matters on appeal and has therefore litigated and argued before several federal appellate courts.
