"Dr. Mangiameli is warm and kind. I wasn't surprised to get my diagnosis as I ignored the lump in my breast for a year. Once I felt it in my armpit I knew it was cancer. He could have scolded me but he was amazing! His staff is fantastic and the PAs are wonderful. I especially love Higer. Hope I spelled that correctly. She is a real cheerleader! I am so glad my GP told me to see Dr Mangiameli. Highly recommend him and his staff!"
