“I've been a patient of Dr. Duncan for over 6 years. I couldn't be happier with the care I've received--the thorough and patient explanations, from testing through fitting of hearing instruments, and the high quality hearing aids. I recommend Duncan-Nulph Hearing Associates to anyone who needs assistance with hearing. They are the best!”

“Outstanding practice! Dr. Duncan was extremely patient and thorough with my 95 year old mother. She is very happy with her new hearing aids and enjoys watching tv so much more, as well as finding it much easier to understand conversations. ”

“Took the time to explain each step of the exam and went over the options for a hearing device and how to get the maximum benefits once I was fitted. Great process!”
