The clinic manager was very nice and had an answer for every concern or question I had! The team is so smart and made me feel comfortable buying hearing aids there! Thanks again Sonus and the wonderful staff at Sonus Glendora!

I got my impressions done for my in-ear hearing aids and I loved the service here! The dispenser who helped us was attentive and very kind. I will be bringing the rest of my worship team to have their impressions done here.
