Our Mission

Our mission is to identify and provide treatment for individuals with hearing loss  and those considered at risk.

Our Philosophy

We strongly believe that hearing ability significantly impacts the quality of life, regardless of age.  Our goal is to not just improve hearing, but to enhance the communication skills of hearing-impaired individuals, their family members and their friends.


The field of clinical Audiology emerged after WWII, when many veterans were returning with noise-induced hearing loss from constant exposure to artillery guns.  The Audiology program at the University of Illinois Medical Center was developed in the late 1940s and as the clinical field began to grow, so did the program.  Audiology became the specialty designated to identify and treat hearing loss in all ages.  In 1983, the Division of Audiology was established at the University of Illinois Eye and Ear Infirmary.
