Patient Comments (1)
in Oconomowoc, WI |
I met Dr. Johnkoski when I arrived via helocopter to the ER. I had an Assending Aortic Disection and required immediate open heart surgery. Dr. Johnkoski clearly explained the required procedure, the risks, and the expected outcomes. He was excellent. After an eight hour successful surgery, and six days in the hospital, Dr. Johnkoski checked in with me every day, and answered all of my questions. The follow up visits were easy to schedule and on time. Dr. Johnkoski saved my life.
