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.

The National Trial Lawyers

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 20 lawyers and has obtained over $750 million in verdicts and settlements for clients.

John obtained a $14 million record failure to diagnose cancer verdict in Illinois for a woman whose doctor delayed her diagnosis of lung cancer. He also obtained a $7.5 million record Illinois Jones Act settlement for a boat worker who was injured in a boat explosion in Alton, IL.

In a birth injury case, John reached a $6.5 million settlement for a young girl who suffers from cerebral palsy as a result of an inexperienced physician’s failure to perform a timely c-section. John also achieved a $5.77 million Federal Tort Claims Act bench trial verdict against a Veteran’s Administration Hospital and a $5.35 million verdict against a Chicago hospital for the family of an 18-year-old woman who died when hospital staff failed to diagnose her with postpartum cardiomyopathy.

John is regarded as one of the leading nursing home negligence lawyers in Chicago for his work on behalf of victims of abuse and neglect. John achieved a $3 million Illinois record nursing home pressure sore settlement for a client. He recovered a $1 million settlement in a nursing home fall case.

John also has experience in all types of injury and accident cases. He achieved a $10 million settlement for a 5-year-old boy who lost his leg when he was run over by a fire truck. In another case, John obtained a $6.5 million settlement for the family of a 32-year-old woman who was killed in a trucking accident. This settlement was a record-high settlement for a Kane County wrongful death claim . Additionally, John negotiated a $6 million settlement for two families who lost six children in an apartment fire, and in another case he reached a Jones Act settlement for $4.5 million for a deckhand whose leg was injured on a barge and required an above-the-knee amputation. John secured a $4.29 million medical malpractice settlement for a 38-year-old woman who died as a result of a hospital and 5 physicians failing to recognize and treat a pericardial effusion, causing cardiac tamponade. He also settled a $3 million medical malpractice lawsuit against Advocate Brommen Hospital in Normal, Illinois.

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 was recently selected by his peers for inclusion in The Best Lawyers in America® for 2013, 2014, 2015, 2016 and 2017 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.

Margaret, Daisy and Bryan. This magnificent cohesive team led by Margaret represented us for my mom's nursing home wrongful death case. They were most patient and responded timely to many questions throughout the entire process. All demonstrated professionalism and extensive knowledge of case and state laws. Their in-depth investigative work uncovered details which were unknown to us and yet sadly confirmed our suspicions. We would recommend the Levin and Perconti Law firm and especially this team. Kathy and Ron
Mr. Levin, Mr. Perconti and the firm handled a medical malpractice suit for my family. During that time, my family and I suffered the loss of my mother. Mr. Levin and Mr. Peconti were more than just our lawyers. Words can’t really express our gratitude. My family and I will always be grateful for the compassion that they showed us. I want to thank you for what you did for my family, and for always being there for us. W.R., Medical Malpractice Client
Our deepest appreciation to the law firm of Levin & Perconti, and in particular to Margaret Battersby Black, in the handling of the lawsuit we field n behalf of our sister who sustained life-threatening injuries as a nursing home resident. Margaret’s representation, guidance, and professionalism gave us the sense that we could put our trust in Levin & Perconti and the final outcome proved that to be true. D.G., Nursing Home Client
I want to send my heartfelt thanks to John Perconti and the Levin & Perconti staff in taking our case. Not only were they so professional but also so caring and thoughtful. It was very difficult going over the facts in our mother's case but they were so compassionate and understanding and allowed us to be with them every step of the way. We were able to sit in on the depositions and we were really able to see how hard they worked on our behalf. M.R.Z., nursing home client
