Our statewide offices have extensive involvement in defending medical malpractice and allied professional liability claims. As a result we have developed contacts with excellent expert witnesses and consultants to assist in the evaluation and trial of cases. Our lawyers are focused on the timely assessment and disposition of claims or lawsuits when that is advisable. However, the extensive trial experience and record of successful verdicts by our lawyers is evidence of our commitment to defending our clients when a verdict is preferable to settlement.

This philosophy has allowed us to be a leader in the field of defending medical professionals. Our caseload volume not only gives us depth and experience, but efficiency as well. 

Our appellate department is one of the most active in the state. It handles appeals not only from our trial attorneys but also from other firms and clients who retain us. The attorneys in our appellate department have handled numerous professional liability cases of significant precedential importance in Illinois, such as Witherell v.

Significant Cases

  • Stephenson v. O, M.D. Defense verdict in federal civil rights case involving back surgery.
  • Magurany v. S Defense verdict in rear end collision resulting in partial paralysis and brain damage.
  • Mondragon v. K.A., M.D. Defense verdict in favor of colorectal surgeon, where plaintiff developed severe incontinence following hemorrhoidectomy and sphincterotomy. Plaintiff alleged that incontinence was caused by an unnecessary sphincterotomy, and that informed consent was not provided for the sphincterotomy because it was not contained within the consent to treatment.
  • Jordan v. Maloney Defense verdict in professional liability and fraud case against home inspector and realtor.
  • Gill v. Aquino, MD (1993) - The plaintiff underwent abdominal surgery in Springfield and was discharged. Not feeling better, he sought care with Dr. Aquino, his family physician and our client. He ultimately had a significant complication that required extensive corrective abdominal surgery. The case went to a jury trial, which found that Dr. Aquino’s delay in sending the plaintiff back to his original surgeon for follow up was the proximate cause of his injuries. The plaintiff was awarded $55,000 and found to be 50% at fault for not going back to his surgeon on his own accord. The original surgeon and hospital settled before trial for $35,000, therefore the net verdict against the doctor was less than the setoff and the doctor owed nothing on the award. The verdict and comparative fault decisions were upheld by the fourth district appellate court and the Illinois Supreme Court.
  • Adkins v. Sarah Bush Lincoln Health Center (1989) - A physician had his hospital privileges suspended in part and not renewed in part. The Illinois Supreme Court found that the suspension of the physician was proper because the physician had notice of the claims against him and the hospital committee took action that it was authorized to take under the hospital bylaws. The Illinois Supreme Court also found that the hospital did not properly follow its bylaws when it denied the application for privileges renewal, however, that issue was rendered moot because of the proper imposition of the summary suspension.
