Our doctors then use proven protocols and a thorough, precise approach that provides solutions using treatment or devices.

To date, more than 90% of all Institute patients have demonstrated measurable, clinical improvement following personalized dizziness therapy. We are fully-equipped to test, accurately diagnose, and treat balance disorders involving all six vestibular canals. We eliminate frustrating and time-consuming travel by providing both diagnosis and treatment at our convenient locations.

Besides being home to one of the country’s most inclusive balance facilities, we have one of the largest audiological practices in the U.S., specializing in hearing loss, education and prevention. We utilize the most sophisticated diagnostic technology available within examination rooms and specialty areas to accurately diagnose and treat your needs.
