Francis P. (Frank) Morrissey is a trial lawyer with a national reputation as a tenacious and highly successful personal injury and medical malpractice attorney. He has won multimillion dollar awards for his clients and his firm has the distinction of winning the largest reported personal injury settlement of a contested liability case in Illinois history securing $90 Million in 2021 for an individual who was involved in a workplace accident.

Not intimidated by deep pocket defendants, Frank has taken on such formidable foes as pharma giant Johnson & Johnson, and locally, Northwestern Memorial Hospital, Rush University medical Center, Loyola University Medical Center, Advocate Health and Hospitals, Lurie Children's Hospital and Presence Health and Hospitals. From Florida to New York to Pennsylvania and back to Chicago, Frank has demonstrated a sophisticated knowledge of case law and won the respect of local judges and opposition attorneys alike as a stalwart litigator for his clients.

With his Irish wit and down-to-earth manner, Frank has charmed numerous juries in high-stakes lawsuits. Recently achieving a $9.7 million verdict in federal court involving complications from gastric bypass weight loss surgery, Frank Morrissey also settled birth injury cases for $10.9 million and $9.4 million.

First selected by his professional peers as an Illinois Super Lawyer in 2005, Frank has been so chosen every year since 2009. His selection as an Illinois Leading Lawyer reflects his ranking among the top five percent of all personal injury lawyers in Illinois.

Such honors demonstrate the pattern he established early in his career. As a young lawyer in 2003, he was named one of the Chicago Daily Law Bulletin's "40 Under 40" Illinois attorneys under the age of 40 whose early success portended future courtroom stardom.

As a result of his extensive experience in medical malpractice cases, Frank has been chosen to be a contributing author to Chapter 10 ("Fact Discovery"), published in Medical Malpractice 2011 Edition and 2013 and 2018 Supplements produced by the Illinois Institute for Continuing Legal Education (IICLE®). Frank is also the Past President of the prestigious Illinois Society of Trial Lawyers, a member of the American Board of Trial Lawyers, and the Past President of the Celtic Lawyers Association.
