About John Simon
John G. Simon founded The Simon Law Firm in 2001 and has built a record of courtroom victories across three decades of practice. The National Law Journal named his firm one of the "winningest firms" in the United States. In roughly 20 months, his firm achieved four nine-figure verdicts totaling nearly $2 billion. His landmark results include a $745 million wrongful-death verdict against a nitrous-oxide manufacturer, a $535 million verdict for a sexual-assault victim at a behavioral health facility (the largest such award in Illinois history), and a $462 million verdict in a trucking underride-guard case.
He obtained his J.D. from Saint Louis University School of Law in 1986 and has taught Trial Advocacy there as an adjunct professor for more than 25 years. He was inducted into the Inner Circle of Advocates in 2014 and has been voted Missouri's number-one lawyer by Super Lawyers peers for seven consecutive years. In 2025, Missouri Lawyers Media named him Influential Lawyer of the Year. He is a past president of the Bar Association of Metropolitan St. Louis.
Proven verdicts and settlements
A St. Louis County jury returned a $745 million verdict against nitrous oxide distributor United Brands and local head shop Coughing Cardinal after finding the companies conspired to sell Whip-It! canisters as an inhalant to a driver who passed out behind the wheel and fatally struck 25-year-old Marissa Politte outside her workplace.
A Champaign County jury returned a $535 million verdict -- the largest known single-plaintiff verdict in Illinois history -- against a psychiatric facility that failed to prevent the rape of a 13-year-old female patient by another adolescent resident.
A St. Louis jury awarded $462 million against trailer maker Wabash National after its defective rear-impact guard failed and allowed a car to slide beneath a trailer on I-55, killing Taron Tailor, 30, and Nicholas Perkins, 23, in 2019.
A St. Louis jury awarded $105 million to tire technician Randy Dorman after a Bridgestone/Firestone RH5 multi-piece truck wheel explosively separated during inflation, fracturing his face, both arms, and wrist, while internal company documents showed Firestone engineers had tracked nearly 100 similar incidents for decades.
Prior results do not guarantee a similar outcome. Each case is unique and depends on its own facts.
