Nancy R. Vidal is an experienced health care trial attorney whose primary practice involves defending health care providers and health care institutions in medical malpractice litigation. Her medical malpractice cases have involved a variety of medical specialties including, but not limited to, emergency medicine, orthopedics, anesthesia, pediatrics, neurosurgery, general surgery and obstetrics. She has first and second chair trial experience, and has successfully argued cases before the Missouri Court of Appeals for the Eastern District.

Ms. Vidal has a keen appreciation for the issues involved in claims against health care providers as she has more than 16 years of nursing experience.

She is also a member of the Lashly & Baer Health Care Advisory Team.

In addition to her litigation practice, Ms. Vidal advises hospitals on risk management and compliance issues, she has lectured on compliance and legal issues with the Medicare Secondary Payer Act and on documentation of medical records. She represents various health care providers in disciplinary matters where their professional licenses are at stake. She has represented providers before the Missouri State Board of Nursing, Missouri Board of Registration for the Healing Arts, the Missouri Board of Pharmacy, the Missouri Department of Mental Health, and the State of Missouri Administrative Hearing Commission.
