Choosing your hearing healthcare provider is a critical component to proper diagnosis and management of hearing loss. Sometimes it can be confusing when deciding who to trust with your first appointment to have your or a loved one’s hearing tested. We believe that knowledge is power, and with so many hearing healthcare options, it’s important to understand the differences so you can make an educated decision that is right for you.
