“I had an excellent experience with Duncan Nulph Associates. Beginning with an updated hearing test after 10 years since my previous test, Dr. Duncan sat with me and explained every aspect of the results, her findings and recommendations, and the path forward to hearing aids. She referred me to an ENT to evaluate for possible issues, and after that we met again to discuss hearing aid options. Again, Dr Duncan explained everything and answered my many questions. All the staff were very friendly and knowledgeable. Appointment scheduling was simple. I felt that I was fully advised on every aspect of beginning my use of hearing aids. I would, and already have recommended Duncan Nulph Associates to others who are experiencing serious hearing loss.”

“After testing my hearing, Dr. Nulph spent time explaining all that pertained to my hearing loss, and gave me peace of mind. It is my first time using hearing aids though I have had my ears tested in the past. She went over different hearing aids and made suggestions that enabled me to decide what would work best for me. The staff is very friendly and I would recommend Duncan and Nulph Hearing to all.”
