“Everything was very well explained to me. I was given time to see how I felt with hearing aides and to make adjustments. I was comfortable discussing my needs in a very friendly environment. I feel I was given excellent care. ”

“For years I haven't been able to hear very well and would say "what" when people talked to me. Now I can hear, thanks to Michelle. She made the whole process go smoothly. Instead of giving her a "5", I gave her a "10". Thank you Michelle. ”

“My daughter selected Duncan/Nulph after reading about the practice on line. As a 86 year old my hearing was impacting my ability to communicate. The practice was professional, caring and focused on improving my hearing. Today I had my first placement of my hearing aides. My daughter cried when she realized I could hear. What a great holiday we will have. We are very fortunate to have found a great physician and practice to diagnose my hearing loss and find the best product with the best on hands education. ”
