Policies & bylaws

We strive to be a transparent, evidence-based, organization that works collaboratively to increase the number of and access to transplants, improve patient outcomes and promote safety.
The OPTN acts through its Board of Directors and committees. They bring a wealth of commitment and technical knowledge to guide the OPTN. Committees address issues of concern in the transplant community.
