With over 25 years of experience in ENT care, Dr. John S. Stewart is an experienced leader in minimally invasive sinus and allergy treatments. Board certified in Otolaryngology & Facial Plastic Surgery by the American Osteopathic Association, Dr. Stewart brings extensive clinical expertise and a compassionate, patient-first approach to the Breathe Better Institute.

He earned a B.S. in Biology, with a minor in Chemistry, from Grand Canyon University and completed his medical training at Freeman Health Systems in Joplin, Missouri. He went on to complete a prestigious fellowship in Neurotology and Skull Base Surgery under the legendary Dr. Michael Paparella in Minneapolis, MN.

Dr. Stewart is known for delivering life-changing results through advanced, in-office sinus procedures that reduce pain, eliminate the need for hospital stays, and get patients back to their lives faster.

Before joining Breathe Better, Dr. Stewart practiced at premier ENT practices in Minneapolis, Starkville, and Phoenix. Recruited by local residents who wanted to bring his exceptional care to North Alabama, Dr. Stewart is now proud to serve the Huntsville community.

Outside of work, Dr. Stewart enjoys hiking, biking, travel, and movie nights with his family. He and his wife, Jennifer, recently relocated to Huntsville with their children—Nohl (17), Scottlyn (5), and their loyal chocolate lab, Cocoa. Their older children, Morgan (21) and Grayson (18), currently reside in Arizona. Together, the Stewarts are excited to explore their new home and give back to the community, both in and out of the clinic.
