    Dr. Nielsen was extremely kind, caring, and knowledgeable. She listened to everything I had to say and was very articulate when answering my questions. Not once did I feel rushed or not listened too. She spent over an 1 1/2 hours listening, evaluating, and answering my questions. By far one of the best doctors I have had.
