    Allegra Hamman took a detailed history. She diagnosed my correctly as a skin infection and put me on antibiotics. She went out of her way to facilitate urgent visits with specialists (Dermatology and Plastic Surgery) for my skin Infection. As a result of her efforts I was seen the following morning by Dermatology and am recovering from the infection. I could not have received better care. I am very appreciative of how she took care of me.
