Physicians

Our physicians strive to provide the highest quality of patient care. While monitoring remotely, they communicate in real time with the technologist and other staff in the OR to assist the surgeon and avoid damage to the patient's nervous system.

Part of our commitment to quality as a Telemedicine Physician Practice under the Joint Commission of Healthcare Organizations includes following these principles.

RTNA Physicians:

  • are on our staff and follow our credentialing policy and procedures
  • participate in regular IONM focused CME
  • practices are limited to your IONM patients
  • quality and responsiveness is constantly evaluated
