Hi my name is Noelle Krockey I’m 22 and I am a two time liver transplant recipient. I was diagnosed with Biliary Atresia when I was 11 weeks old at the University of Chicago. From there my family moved to Minnesota where the search for a donor started. At 6 months old I had my first partial transplant at the University of Minnesota Mayo Clinic. My uncle was my donor and the donor piece lasted almost 6 months until I clotted in my main portal vein. We lived in Ohio at the time, and soon moved back to Illinois where I started receiving care at Ann and Robert H. Lurie Children's Hospital in Chicago. A month before my 3rd birthday we received a call that they had found a match. Two days later I received my second transplant and have had it for 19 years. I am currently working as CNA through Northwestern and going back to school for a degree in Diagnostic Medical sonography. I am also a part of a support group through the children’s hospital called PeerWise which connects kids with similar conditions. I am excited to become part of SPLIT PFEP and connect with other transplant recipients!
