Dr. Zimmer has to be one of the most polite and respectful doctors I have ever met. Those qualities plus what I perceived to be a high level of knowledge and awareness of new technology gives me confidence that I made a smart choice in choosing him to provide my medical care. Other doctors should follow his lead.
