I have severe hearing loss. The team at Advanced Audiology fitted me with an Oticon hearing aid and it was like a miracle! They were very attentive and caring. I am totally impressed.

Leanne is very professional. She explains things very well, listens to my questions and is extremely knowledgeable. Last, but not least, she is a wonderful person.

One of the best medically related visits I've ever experienced and I'm 84 years young! Tiffany and Nancy are two of the most caring, patient people ever!  So glad they were referred to me by a friend!

– Marilyn M.

I didn't realize how much I was missing! My wife no longer has to speak only on my right side. I shouldn't have waited so long to make this life improvement!
