I've recommended Dr. Fischer to a friend who is as happy with him as I have been. He's compassionate, knowledgeable, helpful, understanding and warm. If I have questions about test results, he puts any concerns to rest and usually comments on test results on the same day, which is highly appreciated. An excellent doctor with a top-notch staff of efficient, friendly and kind people.
