He began his career as an attending physician and clinical instructor at the Johns Hopkins in Baltimore, Maryland.

Dr. Dennis has a reputation for listening carefully to his patient so that he can tailor treatment options to meet their unique needs. He also takes the required time to proactively ask patients about their home environment and performs a unique protocol to determine if the patient if suffering from symptoms of mold, mycotoxins or other environmental illness. He adds, “I chose a career in medicine because I enjoy helping people, and ENT combines the best of medical and surgical practice. “I pay special attention to the patient’s environment to determine if the air quality the patients breathe regularly could be the cause of disease. ENT is a specialty that can help most people get better.”

Dr. Dennis treats all aspects of diseases of the ear, nose, and throat with a particular focus on fungal sinusitis and other toxins that can lead to neurological disorders such as migraines due to proximity of the sinuses to the brain. He has been a pioneer in Atlanta for several breakthrough procedures .

Removal of “fungul balls” and the remediation of fungi from the sinuses utilizing novel medical and pharmaceutical techniques.

When he is not working with his patients, Dr. Dennis enjoys spending time with his family, making music, playing golf, and scuba diving.


I am a physician and have suffered with mold allergies and chronic sinusitis for 30+ years. A colleague suggested I see Dr. Dennis for a second opinion before undergoing a second surgery. Dr. Dennis tells me that no amount of surgery will help me until I get my environment and my diet right, AND that he can help me, and I don’t need a second surgery. What? This from a surgeon???? He spent nearly 2 hours with me on that first visit. He did food sensitivity testing on me, explained leaky gut and the role of what we ingest and our immune system, taught me how to clean up my environment and diet, taught me which supplements to use to boost my immune system, and treated the infection and inflammation in my sinuses TOPICALLY!

Today, I no longer have hives, reflux or a reactive airway. My skin has improved, and I didn’t even realize there was a connection! My sense of smell is also beginning to return.
