Representative Matters

Over the last decade, Jason has defended over 100 medical negligence claims. He has been called upon to defend hospitals, doctors, mid-level providers, and nurses in complex, high-stakes litigation involving catastrophic injuries and allegations of sexual assault in the context of medical care. Jason has tried medical malpractice cases to verdict, including as lead counsel. Representative matters Jason has defended include:

  • Madison County: Represented radiologist and group in a lawsuit involving a 68-year-old female patient and alleged missed diagnosis of epidural abscess and spinal infection, requiring emergency multi-level lumbar spine decompressive laminectomy. The patient alleged that our client misinterpreted an MRI to show degenerative changes. After a six-day jury trial, the plaintiff asked for $1.25MM, but the jury rendered a verdict in favor of the defendant on all counts. The defense was based on a denial of any deviation in the standard of care and that the spinal infection existed at the time of the MRI read. Managed all phases of litigation from discovery through trial as lead counsel.
  • Franklin County: Represented general surgeon and group in a lawsuit involving a 63-year-old male who underwent allegedly negligent ventral hernia repair surgery, resulting in complications requiring subsequent revisionary surgery, ischemic bowel, and removal of the small bowel. The patient developed post-operative short-gut syndrome with permanent disability with incontinence. The patient had incurred over $1MM in medical bills. The case was tried before a jury for six-days, and just before the closing argument, the case settled favorably for insured. Managed all phases of trial as lead counsel.
  • Jackson County: Represented a podiatric surgeon in a medical malpractice claim involving a tendon release and reattachment surgical procedure that the plaintiff alleged was performed negligently, resulting in subsequent revisionary surgeries, chronic pain, and partial disability. The defense was based on a denial of any deviation of acceptable standards of care, as well as the assertion that appropriate informed consent was obtained. After more than one full week of trial before a jury, the plaintiff asked for $860K. The jury returned a verdict in favor of the defendant on all counts.
  • Marion County: Represented a podiatric surgeon in a medical malpractice claim involving a calcaneal tendon lengthening procedure, resulting in RSD, subsequent surgery, and reflex sympathetic dystrophy. The defense was based on a denial of any deviation of acceptable standards of care, and a denial of proximate cause. After a jury trial lasting more than one full week, the plaintiff asked for $860K. The jury returned a verdict for the defendant on all counts.
  • Saint Clair County: Represented OB/GYN in a lawsuit involving bilateral tubal ligation, D&C, and thermochoice balloon ablation resulting in an undiagnosed uterine perforation. After a two-week trial, the jury rendered a defense verdict.
  • Saint Clair County: Represented a neurosurgeon who followed a 42-year-old male patient after a Chiari malformation surgery performed by a partner. The patient allegedly developed bacterial meningitis, resulting in permanent brain injury and permanent disability. Our neurosurgeon client was dismissed without payment following depositions of all experts.
  • Jefferson County: Represented a certified registered nurse anesthetist and group in a wrongful death case involving alleged failure to protect the maternal airway during an episode of vomiting shortly after labor and delivery. Our defense of the lawsuit involved not only standard of care but also causation, given significant evidence that unforeseeable amniotic fluid embolism had occurred. Following defendants' expert depositions, the lawsuit was voluntarily non-suited by the plaintiff without payment on behalf of clients.
  • Saint Clair County: Represented OB-GYN and group in a lawsuit involving alleged negligently performed bilateral Salpingo-oophorectomy on a 58-year-old female for an ovarian lesion. Subsequent imaging revealed residual adnexal cystic tissue and mass, resulting in a subsequent surgery performed at a tertiary center. Following depositions of the plaintiffs' experts, the case was dismissed on behalf of OB/GYN and group without payment.

Jason has also defended various healthcare providers who were voluntarily dismissed without payment in the following cases:

  • An interventional cardiologist and group in a lawsuit involving an alleged negligent erosion of pacemaker device implant for a 70-year-old male patient.
  • An emergency department physician and her employer in a wrongful death lawsuit involving alleged failure to give tPA to patient with saddle pulmonary embolus.
  • Two certified assistants and their primary care employer in a medical malpractice lawsuit alleging a lack of informed consent and negligent prescribing of oral contraceptives that resulted in a DVT.
  • An internal medicine physician in a wrongful death lawsuit involving allegations of failure to give blood thinner resulting in a stroke and subsequent death.
  • A pediatrician in a medical malpractice lawsuit involving alleged negligence in applying a bandage around the finger of an infant resulting in amputation.
  • A hospital in a medical malpractice case involving an alleged knee injury sustained to a patient while disengaging exercise equipment.
  • A podiatric physician in a podiatric malpractice lawsuit involving an alleged failure to remove broken hardware following foot surgery and resulting in disability.
