  • Practice Areas
  • Representative Experience

    Throughout her career, Ms. Nathan has aggressively defended her healthcare clients. She has obtained defense verdicts as first chair counsel in multiple medical malpractice trials. She also has obtained numerous case dismissals without payment or by way of motion at the earliest possible time after the suit has been filed.

    Selected Notable Accomplishments Include:

    • Obtained a voluntary dismissal of an otolaryngologist in a matter involving a woman in her early 50’s who suffered a stroke after undergoing non-cosmetic septoplasty. The case was ultimately dismissed following the depositions of numerous treating physicians who questioned causation for the plaintiff’s injuries.

    • Prevailed on a motion for summary judgment on behalf of a hospital nursing supervisor in a case involving Theophylline toxicity resulting in brain damage to a young child. The motion was granted on the basis that the nursing supervisor had no independent liability as an employee of the hospital. The case was subsequently settled by other parties for $12,000,000.

    • Obtained a not guilty verdict at trial in Cook County, a very plaintiff’s friendly jurisdiction, in a case brought against our client, a home care agency (and the target defendant), as well as an internist and orthopedic surgeon involving the alleged failure to properly monitor INR levels in a patient on Coumadin following hip surgery leading to a subdural hematoma and death.
