I knew I had hearing loss and I had purchased aids in Michigan. After about seven years, one of them began to malfunction; I knew I needed help in replacing the hearing aids. I was tested again and Dr. Hellenkamp was able to retrieve my old testing online. My hearing had declined none, I was able to try a pair of aids before purchase and found them to be awesome. Dr. Hellenkamp and the staff of Triangle Hearing Services were excellent with their service. Everyone at the office, the receptionist and Dr. Hellenkamp were excellent with their service. I hear beautifully now and miss nothing of conversations. I feel alive again.
