Dr. Fischer and his staff were very well organized and prepared to make the most of a short appointment. Blood tests were done upon arrival and the doctor appeared with fill knowledge of the results. It was encourageing to me when he recommended the next appointment in 6 months, indicating satisfactory results so far. My condition was apparently stable since the first appointment more than a year ago.
