William A. Cirignani has focused his career on helping clients in the Chicago area through litigating medical malpractice and serious injury cases. With more than 25 years of experience in the field, he brings a wealth of knowledge to his clients who need help at a stressful time in their lives.

After completing his legal degree at the Northwestern University School of Law in Chicago, Illinois, he worked as a defense lawyer in Arizona for medical personnel and businesses that faced construction and product lawsuits. He then moved to Chicago and expanded his work into the field of employment and wage disputes while continuing work in medical malpractice defense representation.

In 1995, he joined the firm that eventually became Cirignani Heller & Harman, LLP, which has won and negotiated several multimillion-dollar court verdicts and pretrial settlements on behalf of injury victims and their families. Cirignani, Heller & Harman is unique in that it practices exclusively in the field of medical malpractice, and many of its lawyers are also medical professionals--Stan Heller is a board-certified cardiologist from Johns Hopkins, James Harman was a certified respiratory therapist before becoming a lawyer, and Patrice Koch remains a registered nurse. CH&H successfully leverages their combined medical and legal expertise to provide clients state-of-the-art legal representation, and a review of their cases free of charge or commitment.

Mr. Cirignani serves many types of clients, including professionals, athletes, the disabled and artists. He defends the need for justice for the clients he represents and places a high priority on integrity and honesty. As a former defense attorney, he understands the workings of defense lawyers in medical cases and uses that knowledge to fight for the rights of those he represents.

Mr. Cirignani is a member of the American Bar Association, the American Association for Justice and the Illinois Trial Lawyers Association, among other professional organizations. He is admitted to practice in Arizona, Illinois and Georgia. He is also licensed to represent clients before several U.S. District Courts, including the District of Arizona, the Northern District of Illinois, the Southern District of Illinois and the Northern District of Georgia. He has been licensed to hear cases before the U.S. Court of Appeals for the 7th Circuit. He has received several honors and awards, including recognition as a top lawyer in at least four professional publications, including the Leading Lawyers Network, Chicago Lawyer Magazine's Top Lawyer In Illinois, Strathmore's Who's Who Among Medical Malpractice Lawyers and Marquis Who's Who in American Law.

  • — B.G. special administrator v. Provena St. Joseph’s Medical Center, et. al., $4,500,000.00 Wrongful Death—Verdict (Illinois): The patient, a 43 year-old father of four, came to the emergency department with severe chest pains. A CT scan revealed that the cause was likely an aortic dissection (“AD”), a condition that can be quickly fatal if not treated right away. The ER doctor ordered a test to confirm the AD but that test was never done and consequently the AD was never treated. Seven hours later the man died. The case went to verdict before a Will County jury who found two of the four defendants responsible.
