She seemed very hurried. I was in and out in 10 minutes. But she knows her stuff. She found my lesion on ultra sound in about 4 seconds. I need surgery but had travel plans approaching. She assured me she would get my surgery done before my travel date and it is indeed scheduled. I am very grateful for that.
