To The Nissen Family & Friends: I am so overcome with grief for your family's loss, in more ways than you will ever know. I was following John's profile, especially when he had to see a nephrologist. My son, who is 31, is a dialysis patient in total kidney failure. He is trying to have this surgery to help him get in shape to try for a transplant. I was so hoping that John would have a wonderful outcome from this. You are in my thoughts. I can only imagine your pain.
