Meet Our ENT Specialist: Dr. Mark Harrison

I treat my patients like family and truly care about restoring their health.  

When your allergies are flaring up, or you’re no longer able to breathe out of your nose, it’s time to take action. Conditions of the ear, nose, and throat can impact every aspect of your life, from your work to the enjoyment you get from daily activities. You are not alone!

Dr. Mark Harrison understands how frustrating it is to battle sinus, allergy, and other ENT problems. He is committed to providing each patient with lasting relief through the most advanced, minimally invasive treatments that are both safe and effective.

Dr. Harrison is an otolaryngology (ear, nose & throat) specialist that has been practicing for decades. He graduated from the University of South Alabama School Of Medicine in 1998 and specializes in ear, nose, and throat, rhinology, and more.

Dr. Harrison is truly a great and caring doctor. I had sinus surgery last month and for once in over 8 years I can breathe, and I don’t have to take allergy meds anymore! I would HIGHLY recommend Dr. Harrison. Also, his whole staff are so nice and care about your needs.

I have been to at least 3 different ENT doctors in the last 15 years and no other doctor has done more for me than Dr. Mark Harrison. Being able to breathe immediately after surgery was amazing! His staff is extremely professional
