“I had been resisting getting hearing aids for years; but as a trial attorney i need to hear in court! Dr. Baker and Monique were great; accommodated my schedule and has even cleaned them out for me when the wax builds up. Her office is the type that you need when it is going to be a long term relationship. I am lucky she has an office in TO as well as Simi Valley. ”

“The product is awesome! I like the audiologist and her staff! I lost one aid, I wear 2, and Ellen Barker found me an affordable replacement set. When one has to go without and it's not realized it's missed, but then it's restored, you're overwhelmed to tears. Well it was like that. ”

“I give them 1 star because they couldn't program my hearing aids. I had my own hearing aids. I went there to have a hearing test and to have them program those hearing aids for me but they couldn't program them. They charged me for the hearing test.”

Received 03/19/2018Official Response from Decibel Hearing Services - Thousand Oaks:“Hi Ken. I am sorry that I was not able to program your aids. Unfortunately, your aids were originally purchased in another country and we do not have access to the software needed to program them. I did contact the manufacturer to see if they could send me the software needed to program the aids, but even they were unable to help. I appreciate your feedback and hope we can assist you with your hearing needs next time. Ellen”
