John J. Perconti

Founder and Senior Partner

Meet John—Advocate, Expert, Family Man, Trial Attorney

John J. Perconti is a nationally recognized attorney and one of the country’s leading medical malpractice experts, with extensive experience in federal and state courts. As one of the firm’s founding partners, he has worked tirelessly to build Levin & Perconti into one of the nation’s best personal injury firms. John’s excellent record of success representing clients in injury, elder abuse and wrongful death cases can be attributed to both his acclaimed skill as a lawyer and to his acute understanding of what it means for a family to experience a loss.

When John was just a 9-year-old boy growing up in Morton Grove, his father died suddenly, leaving John and his brother and sister to be raised by their mother, who worked as a nurse, and their grandparents. Losing a loved one at such a young age taught him a difficult but valuable lesson, that life is fragile and precious, and that when someone dies the lives of family members are forever changed. From a young age, John knew that he would pursue work helping people. His commitment has only deepened over the years as he went on to marry his wife, Toni, and become a father to his two daughters, Morgan and Paige.

Initially interested in pursuing medicine, John spent two summers as a Page in the U.S. House of Representatives and two more as a tour guide of the U.S. Capitol. It was there he discovered his love for the law. He changed his major at the University of Illinois from pre-med to pre-law and continued on to John Marshall Law School for his law degree.

John still found a way to put his interest in medicine to good use. His in-depth knowledge of complex medical issues has allowed him to achieve record-setting multimillion-dollar verdicts and settlements for his clients over the course of his career spanning more than 35 years. In 1992, he merged his practice with Steven Levin, and now the firm employs more than 30 lawyers and has obtained over a billion dollars in verdicts and settlements for their clients.

John is an active member of the Illinois Trial Lawyers Association, American Association for Justice, Illinois State Bar Association, Chicago Bar Association, Society of Trial Lawyers, The Association of Plaintiff Interstate Trucking Lawyers of America and The Justinian Society of Lawyers, and has been a strong voice against tort reform. He is also a member of The National Trial Lawyers, an organization composed of The Top 100 Trial Lawyers from each state, and is a Fellow of the Litigation Counsel of America.

John has been selected by his peers for inclusion in The Best Lawyers in America® since 2013 in the field of Personal Injury Litigation – Plaintiffs. He has received an “AV” rating from the Martindale-Hubbell American Law Directory, indicating preeminent legal ability and very high ethical standards. He has also been named one of Illinois’ top litigators by Leading Lawyers Network and achieved a Lead Counsel Rating in Elder Law.

John is also included in Chicago Magazine’s Illinois: The Top 100 list, a listing of lawyers who topped the Illinois Super Lawyers nomination, research and review process. He has been named an Illinois Super Lawyer every year since 2005.
