Kari S. Peterson is a founding partner of O’Leary, Shelton, Corrigan, Peterson, Dalton & Quillin, and represents clients throughout the country and in St. Louis. She handles cases of catastrophic injury, trucking accidents, wrongful death, electrocutions, auto accidents, premises liability, product liability, workplace injuries, dog bites, pharmaceutical and drug litigation, and workers’ compensation. Throughout her career, she has represented the rights of clients against large corporations and Fortune 500 companies with a commitment to never giving up.

Named one of Missouri’s Top 40 Under 40 Litigation Lawyers by the American Society of Legal Advocates, she was also named by The National Trial Lawyers as a Top 10 Trial Lawyer in Missouri. Martindale-Hubbell also gave Ms. Peterson the Client Distinction Award, and KC Magazine has repeatedly listed her as a Top Plaintiff’s Personal Injury Attorney.

While earning her Juris Doctor from the University of Missouri-Kansas City, Ms. Peterson was given an American Jurisprudence award and was an editor for The Urban Lawyer law journal. She has worked with insurance companies and organizations in the past to defend them against clients who are injured, but she uses that experience now to help injured individuals, which is her true passion.
