When Greg first learned about a rare disease affecting his brother, he had no idea that the illness would come to define his own life, or that his search for answers would take him on a journey going back generations to his Irish ancestors.
Greg grew up in an active family. As a climbing instructor, guide and designer of outdoor equipment, his love of the outdoors was at the center of his life. So when the keen rock climber started having nerve problems in both wrists that made it difficult for him to grip tightly, he was crushed and knew he needed help. At first, he thought it was carpal tunnel caused by the repetitive flexing needed in the sport. But after further testing, Greg was diagnosed with polyneuropathy of hereditary ATTR amyloidosis (hATTR) - the same disease that had robbed his beloved older brother of his independence, ability to function and eventually, his life.
