Meet our Team

The Illinois Neurological Institute Sleep Center treats adults, children, and infants with sleep disorders. Your team includes two board certified sleep specialist neurologists, Sarah Zallek, M.D., the center director, and Bradley Gleason, M.D. Four sleep specialist nurse practitioners and physician assistants work very closely with the physicians to provide comprehensive sleep care to all patients. We have two state-of-the-art centers located in Peoria where all evaluation, testing, and follow up take place.
