S. Mark Overholt, M.D.

Board Certified: American Academy of Otolaryngology - Head and Neck Surgery

Mark grew up in Knoxville, Tennessee, and went to Webb School of Knoxville for High School and Stanford University

As a general otolaryngologist and head and neck surgeon, like many others in the team, he sees patients for half of the day and operates the other half of the day.

Serving as president of the group, he is involved in administration decisions and planning, ensuring the ENT practice is always striving for success.

He believes his partners are all well-educated and compassionate physicians and finds it a joy to practice caring for the wonderful people of East Tennessee.

Nothing fulfills Mark more than solving a problem for a patient who has been suffering for a while, whether it is as simple as letting them breathe more easily, stopping their sinus infections, or walking through their cancer journey towards a cure.

Mark loves his job and is honored to walk out the door with a smile on his face each day.

Outside of work, Mark is an avid fly fisherman. He enjoys traveling to new places where he can experience different cultures with his family. He also loves history reading and is a passionate cook.
