Dr. Iennusa takes great pride in treating his patients and truly treats each one as he would treat a member of his family. His goal is to provide the highest quality care to his patients while having fun in a relaxed atmosphere. When not in the office, Dr. Iennusa consistently attends continuing education courses in order to stay abreast of the latest orthodontic technology that allows him to provide state-of-the-art treatment. He is an avid LSU fan (and former snare drummer for the LSU Golden Band from Tigerland) and can often be found at one of his children's athletic events or with his son chasing redfish and speckled trout.
