California Ear Institute was founded in 1968 as the first practice to be dedicated solely to Hearing Health care in the United States. Our world renowned surgeons have provided more than a quarter of a million visits for patients with surgery, medical, hearing aid, Cochlear Implant, Facial Nerve Disorder and Cranial Base Disorder needs. CEI is Northern California's premier site for treatment of ear related disorders and is highly ranked among the world's Centers of Excellence specializing in hearing and balance related disorders. The Institute is famous as a site of referral for patients from whom treatment has not turned out as expected – particularly those who require second opinions and/or revision surgical procedures. CEI accepts most major private insurance plans plus Medicare.
