Nurse Hamman is very pleasant and respectful. She was very thorough, as usual, and was careful to address all of my pre-op paperwork and review all of my current medications and allergies. She was very careful to address all issues pertaining to my 2nd upcoming surgery, as well as to discuss the importance of my stopping Mounjaro one week before surgery to prevent a complication. I think that she is very competent and that she provided excellent health care.

Allegra was great. The preop appt was with her because I was told my PCP had no openings; however PCP then mentioned she did have a time slot. Both PCP and I would have preferred she do the visit. Still, visit with Allegra was perfectly fine.

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.
