“Reference provided by a friend of my wife. All subsequent support has been total support and assistance in obtaining and using my hearing aids. Recommending and providing my Caption call device was over and above support. My experience and total support provided me has been well over and above normal support.”

“My mother had a hearing aid that had gotten broken. When I called the office where she had purchased it, I was told they would have to send it away for repair and it would take several weeks. There was no one there who would even look at it. A friend had recommended Dr Duncan so I called the office and was told to bring the hearing aid in and they would look at it. They had the hearing aid fixed in minutes saving my mom from having to go without. The staff at this office is always friendly and helpful. Thank you for your excellent customer service. ”
