An exceptional advocate for complex insurance defense matters

John Kemppainen expertly guided our company through a challenging premises liability lawsuit. His 30+ years of courtroom experience in Missouri and Illinois were immediately evident. He provided a clear, strategic defense that resulted in a favorable settlement. His AV-rating and Super Lawyer recognition are well-deserved. John is a consummate professional who combines deep knowledge of insurance litigation with practical, client-focused advice. I would not hesitate to recommend him to any business facing significant liability claims.
