Read More About the History
of MSR West.

For years, we have provided hearing care professionals in these areas with cutting-edge audiology equipment from the world’s most renowned manufacturers. Taking a consultative approach, we work with you to learn your needs and help you pick which of our 160+ screening and diagnostic instruments best suits them.


Additionally, our staff of NASED-certified service technicians is here to ensure your instruments provide reliable results at all times. They’re trained to repair and calibrate ALL audiology equipment, and their close proximity to you allows them to service your instruments in a fast and efficient manner, saving you time and money.

Your Local Experts

Our business is headed by industry veteran David Chiaravalli, a former Product Manager at Bernafon and Sr. Product Manager at Interacoustics who has the years of experience and vast expertise to help you find the right audiology equipment for your unique needs. On a typical day, you may find David enjoying a decadent pao de queijo (Brazilian cheese bread) while listening to a diverse Spotify play lists ranging from alternative rock to underground rap.

David draws inspiration from his customers who diagnose and treat hearing loss on a daily basis. In fact, a touching relationship between a hearing-impaired gentleman and an audiologist is what inspired him to make a career in the hearing care industry. It’s that care for others that drives him to exceptionally perform his job duties every day.

If you have any questions about our equipment or services, reach out to David today. He will be more than happy to assist you.
