My first visit with Dr Hemmersmeier was very good. He discussed my plan of care very thoroughly and checked all my vitals with a very caring attitude. He also had a great sense of Humor in a very appropriate way that not many doctors have. I highly recommend Dr Hemmersmeier for any age patient care.
