This is a doctor you need to keep. One of the best visit I have had in a long time. Dr Nieman was on time, friendly and to the point in a nice way.. He made you feel he really did care about you and your problem. He is one doctor that I look forward working with. All of my doctors are ok, he just takes a little more time and is easy to understand.
