Kenneth T. Lumb joined Corboy & Demetrio as a Chicago personal injury and medical malpractice lawyer in 1995 after a tour of duty in the United States Army.  Ken was named Partner in 2015 and Managing Partner in 2019.

As a captain in the Army's Judge Advocate General's Corps (JAG Corps), Mr. Lumb served four years as the Medical Claims Judge Advocate at Walter Reed Army Medical Center in Washington, D.C. His duties at the Defense Department's largest medical facility included medical malpractice defense and hospital law. He has also served as a Special Assistant United States Attorney. In 2003, he was mobilized in support of operation "Enduring Freedom" and spent six months on active duty at Walter Reed for which he received a Meritorious Service Medal. Mr. Lumb is currently a retired major in the U.S. Army Reserve.

As a personal injury and medical malpractice trial lawyer at Corboy & Demetrio, Ken has obtained numerous multi-million dollar verdicts and settlements on behalf of his clients. He obtained an $11 million verdict on behalf of a child who suffered brain damage at birth; a $10.5 million verdict for the estate of a woman who died after being improperly anesthetized for hip surgery; a $1.75 million verdict for the family of an infant who died as the result of medical negligence; and a $1.7 million verdict for the family of a man killed by a packaging machine at a Nabisco plant. He has also secured, along with partner, Philip Corboy, Jr., a record-setting settlement of $7 million for a woman who was injured when she was struck by a malfunctioning automatic door as she entered a Target store.

In addition to his trial work, Ken is an active member of many legal organizations, including the American Bar Association, Chicago Bar Association, American Association for Justice where he is Chair of the Federal Torts and Military Advocacy Section, Illinois State Bar Association, where is Chair of the Standing Committee on Military Affairs, and the Illinois Trial Lawyers Association, where he serves on the Medical Negligence Committee.
