“Kaitlyn and Karen are both excellent. They provide top notch technical and client service, instruments, responsiveness, all one could hope for and more. ”
“So, I went to see Dr. Kaitlyn Sheapp over at the Preferred Hearing Center to finally get an upgrade for my old hearing aids. Let me tell you, it was a breath of fresh air. You go in expecting just the technical stuff, right? But Dr. Sheapp was different. She has this way of really listening—not just to your ears, but to what you're actually saying. She didn't rush; she was thoughtful, kind, and you could tell she genuinely cared. It made the whole process feel easy and comfortable. Honestly, the difference it's made is hard to put into words. I'm so glad I went to her. If anyone you know is looking for that kind of personal, top-notch care, I can't recommend her enough.”
