“I am a satisfied patient of doctor Krupa. He was professional, kind and very knowledgeable in his field. I felt comfortable and optimistic when he explained how he could help me. He fit me with an amazing hearing aid and showed me how to use it, I can’t begin to tell what a difference the aids have made for me, it’s amazing!”
