He read to me comments made by radiology dept. where I get my dialysis catheters. That information was mostly not true what they wrote about me. That was shocking.

I trust Dr. De Castilla. He shows respect and knowledge and care. He includes my daughter in discussion when she's there, and asks about her when she's not.
