Donald Guillen,


Dr. Donald A. Guillen earned his doctorate from Towson University and completed his clinical fellowship at the Hearing Assessment Center. During his doctoral studies, his research focused heavily on the effect of degraded listening conditions (background noise and reverberation) on cochlear filtering as well as auditory brainstem encoding in normal and hearing impaired individuals. In particular, he was interested in understanding why hearing impaired individuals have a difficult time understanding speech in noisy environments while normal hearing individuals do not. He utilizes this in-depth understanding to properly treat hearing impairment clinically, as the applicability of this research is integral to the recommendations he makes on a daily basis. He now dedicates much of his time to the thorough evaluation and treatment of individuals with chronic tinnitus and hyperacusis. He has established himself in the community as a caring and well-versed tinnitus professional who has treated and assisted many of these individuals.
