We are open and seeing patients while providing the safest possible environment. In accordance with hospital and CDC guidelines, we are continuing to screen all patients prior to their appointment and are limiting the number of patients for social distancing. We request you do not bring anyone with you to your visit unless you have mobility issues or the patient is a minor. Our staff is continuing all sterilization protocols and wearing masks. If you have a personal mask or other facial covering (scarf, bandana, etc.), please bring it with you for your appointment. Additional information about facial coverings can also be found here.
We are offering telemedicine appointments for appropriate new and current patients during the COVID-19 virus outbreak. If you have ENT-related concerns and a smartphone with access to video and text messaging, you are a candidate for a telemedicine visit. Please call us at (865) 244-4396 or contact us through our patient portal with any questions, concerns, or to schedule an appointment.
