I have been a professional pilot with a hearing deficiency since I was 18 years old. Over the past 56 years I have had more than 60 audiograms from a number of different specialists. Dr. Scarf & Audiology Innovations have been the most professional I have experienced, and very pleasant to work with. There have been huge advancements in hearing technology and they are at the very top of the business. Hal Rainforth
