Each AlphaNet Coordinator has Alpha-1 Antitrypsin Deficiency and, thus, is able to uniquely understand the issues and concerns of other individuals living with Alpha-1. AlphaNet Coordinators are spread across the United States and subscribers to AlphaNet are assigned to a specific AlphaNet Coordinator based on the augmentation therapy prescribed and their geographic location.
