“I have been a patient at California Hearing Centers for three years. I have significant hearing loss and require aids in both ears. California Hearing Center staff has been professional, helpful, I'm skilled. Recently they have worked with me to minimize discomfort with earbuds. Patiently and without cost. Hearing aids are very costly. But in order to hear I must have them. So it's critical that I have skilled professionals to help me make the best use of the technology. California Hearing Center staff has done that.”
