Your visit begins with an unhurried conversation about your hearing history and the moments in daily life where hearing feels harder. A hearing test is used to determine whether you could be helped by a hearing aid, and our Board Certified Hearing Instrument Specialist walks you through each step and reviews your results with you on the spot. Appointments take about an hour.
If a hearing aid makes sense, we discuss options matched to your hearing, lifestyle, and budget, and because we are independent, our guidance is driven by what fits you rather than any single brand. There is never pressure to buy.
Yes. We accept insurance from many companies, and because plans and networks change often, the best way to know your benefits is to let us verify them for you before your visit. Give us a quick call or text and we will check your coverage and explain what to expect.
