M atthew Kaminski has built a thriving medical malpractice defense practice thanks largely to the results he’s earned in the courtroom. At Hall Prangle, Kaminski has earned a reputa- tion for fiercely, and successfully, representing healthcare pro- viders, employers and businesses in high-stakes litigation. Kaminski’s work includes defending hospitals, physicians and other healthcare providers in complex medical negligence claims, while also representing employers facing allegations of discrimination, harassment, retaliation, whistleblower claims, wage-and-hour disputes, contract conflicts, trade secret matters and non-compete litigation. His litigation experience also extends to product liability and federal civil cases across the country. The diversity of his practice shows just how comfortable Kaminski is in tackling difficult legal and factual issues. Kaminski has developed a reputation for breaking down highly techni- cal concepts into arguments that judges and juries can easily understand. “He is well-spoken, confident, knowledgeable and persua- sive,” said Jessica Acuna with the Chicago office of Swanson, Martin & Bell. “He is hardworking and someone you want to see as a co-defendant on one of your cases.” Colleagues say that Kaminski’s preparation and command of both the facts and the law allow him to simplify compli- cated medical and legal issues without sacrificing accuracy,

an important skill when defending clients in cases involving sig- nificant financial and professional stakes. “He is very driven, knowledgeable in the law, an astute litiga- tor and unfailingly courteous,” said another of his peers. Before joining Hall Prangle, Kaminski served as an assistant Cook County state's attorney in the Civil Actions Bureau, where he defended Cook County and its elected officials in both fed- eral and state courts. His work included employment litigation, civil rights claims and contract disputes, giving him valuable courtroom experience early in his career while representing one of the nation's largest local governments. Kaminski’s commitment to advocacy dates to his days at the University of Dayton School of Law. There, he earned the Order of Barristers honor, recognizing excellence in trial advocacy, and competed as a member of the school's Moot Court team. He also received the CALI Award in Appellate Advocacy. Peers describe Kaminski as knowledgeable, driven and un- failingly courteous, qualities they say distinguish him even in contentious litigation. They praise his confidence, persuasive communication style and professionalism, noting that he re- mains focused on resolving disputes despite difficult opposing counsel. Those attributes, combined with his extensive court- room experience and preparation, have helped Kaminski suc- cessfully defend cases against many of Chicago's most talented trial lawyers.
