For hearing, balance and dizziness

Vestibular and audiology testing

Comprehensive testing services

There are a range of tests to help diagnose hearing, dizziness and balance disorders. Legacy Vestibular and Audiology Lab at Legacy Good Samaritan Medical Center offers advanced, complete testing. After the testing, we explain the results and offer recommendations for treatment. 

All testing is performed by doctoral-level audiologists in a caring, comfortable clinic; for follow-up, our clinic works closely with Legacy physical therapists who specialize in balance and vestibular care.

For our younger patients, we partner with Randall Children's Hospital at Legacy Emanuel to provide state-of-the-art testing and newborn hearing screening.
