“Dr. Duncan was referred to me by a relative who is a patient and was pleased with Dr. Duncan's knowledge in regards to hearing loss. She has now been my audiologist since I began wearing hearing aids. I was doubtful of their benefit but I have adjusted very well to the improvement. Dr. Duncan is respectful and helpful and explains the equipment and their use very well. It has been an easier experience than anticipated.”

“Dr. Duncan has been professional, thorough, and personable in every interaction that I have had with her. I have been working with her from initial diagnosis of hearing loss, selection of the proper hearing instrument, and through 3 generations of hearing aids. I really like her "style". The office staff is efficient, friendly, and easy to do business with. Overall, they are an organization that works well together to provide great service to their clients,”

“We needed to find someone new to help my mom with her hearing as our previous audiologist's office was non-handicapped accessible. Duncan-Nulph was recommended by a friend. I'm so glad. Everyone is helpful, professional and very nice. My mom has very sensitive ears and they removed the wax painlessly and fitted her with amazing new hearing aids. My husband and I will be making an appointment with them. We highly recommend them as we feel they are truly the best.”

“True professional service!!! I am truly amazed of how well I’m hearing now. I guess I didn’t know what I was missing. The first time I put the hearing aids in was a very emotional moment for me. Thank You, Michelle! And thank you to everyone at Duncan-Nulph!”

“Very professional people. Learned a lot about my hearing loss from the testing results. Dr. Michelle answered all of the questions we had. She explained everything very thoroughly as we went through the process of testing, fitting, and use of the hearing aids. I have been very satisfied with their service and would recommend them to anyone that is having issues with hearing loss.”
