About Us

Patients who seek treatment from Lemme Audiology can count on finding a reason to love their Audiologist and trust in them. The truth is hearing is often a second nature to many, meaning it doesn’t always get the attention that’s needed. This is why at Lemme Audiology Associates, we take the time to educate our patients about hearing and hearing loss, how hearing loss impacts daily life, and how treating their hearing loss can improve their overall quality of life. 

Our audiologists will listen to your concerns, questions, and challenges and make sure that your treatment plan is the perfect fit. From hearing aid services, to tinnitus, to balance issues, we will find the right solutions for your individual situation together so that you can keep doing the things you love.  

Lemme’s state of the art, vestibular/balance center allows us to provide the most comprehensive diagnostic assessments in the region. For patients who are experiencing dizziness, vertigo or balance issues, this comprehensive evaluation provides essential information to determine the etiology, cause and proper treatment for your dizziness or balance issues.
