My hearing problem started after serving 3 ? years as a crew chief on B17 bombers. We didn’t use ear plugs. A friend told me about Donella Hellenkamp. I met Donella – a very intelligent and caring individual – and she did all the necessary testing and recommended various hearing devices. If you have a hearing problem I recommend you go to Triangle Hearing Services and ask for Donella. I guarantee you will be satisfied with the results!
