“I can't say enough about Summit Hearing Aid Center. Dr. Leslie Herman came highly recommended by other doctors and also through a friend of a friend and it's easy to see why. The care and education I received, and continue to receive is invaluable. Without the expertise to find the devices that are best for my situation I would not be able to function in a social setting or communicate with others in any type of public interaction. Isolation was creeping in. You can't put a price on the quality of service provided here! ”

“In early summer, I lost the hearing in one ear and could not imagine what I could do to improve my situation. I visited Summit Hearing Aid Center and was fitted with a hearing aid in my good ear that enabled better hearing and the expectation of further help in future from a new aid being developed. ”
