I wish I could give them TEN STARS! After moving to Knoxville, I went to them for new hearing aids. This is my third set so I knew the drill. But what I did not know was how wonderful and caring a hearing aid provider could be. Mark was so patient and persistent with an issue that was totally the fault of my phone but he refused to give up. It was resolved and I hear better than ever. And as he predicted, I enjoy music now in a way I have not for many, many years. I cannot express how wonderful these folks are. Go see Mark. You will not be disappointed.
