Quote on why you do what you do: Music has been the most important part of my life for as long as I can remember. Being able to give people the ability to enjoy music again and connect with the world around them is the greatest motivator for me to provide the best patient care at Hearing Unlimited.

Aaron R. McElhinney Licensed Hearing Instrument Specialist
I’ve been with Hearing Unlimited for 7 years (14 years in the industry), and I love the fact that I always have the freedom to “Do the Right Thing”. I never have to feel like I’m trying to make “a round peg fit into a square hole,” like I have at other practices. We truly have the freedom to choose the best product for each of our patients, based on their unique needs and preferences as individuals. It’s a blessing to be able to help people to hear and understand better every day – to assist them in restoring their relationships, which are founded upon communication.
