What is regional administration?

The U.S. is organized into 11 geographic regions. Regional administration unites UNOS with the donation and transplant community in these regions. Regional administrators engage with members in each region as a resource and liaison to all things UNOS. Contact your regional administrator for questions about the region, OPTN policy or compliance, and volunteering. If you have other questions and aren’t sure who to contact at UNOS, let your regional administrator know and he or she will get you connected.

Regional administrators also convene the transplant community for in-person regional meetings that focus on consensus-based policy development and information-sharing. You can meet your regional administrator and UNOS leaders face-to-face at regional meetings held twice a year during the spring and fall public comment periods. Regional meetings are the place to learn about advancements in the field of donation and transplantation,  help shape national transplantation policy, and engage with regional peers — learn, discuss, and get connected.

In addition to convening regional meetings, regional administrators work with regional nominating committees to identify volunteers for OPTN/UNOS committees. If you are interested in learning more about volunteer opportunities, reach out to your regional administrator or visit the OPTN website.

Learn more about your region or view the states comprising each region on the OPTN regional map.
