In the mid 1980’s, a group of transplant patients at the University of Pittsburgh Medical Center saw the need for an organization to help transplant recipients and candidates cope with the challenges they experienced in the transplant process. Out of this group TRIO was established, and in 1987 was incorporated as a not-for-profit organization. It was soon determined that TRIO could best serve the transplant community by becoming an international organization and in 1994 moved its headquarters to Washington D.C.

​TRIO continues to serve transplant recipients in many regions of the nation, with chapters in California, Texas, Washington D.C., New York, Ohio, Florida, Kansas Pennsylvania and Oklahoma among others. In addition, there is an international chapter in Japan.

As the need for organ transplantation increases, so too does the voice of TRIO. The U.S. Department of Health and Human Services, Department of Transplantation (DoT) recognizes TRIO as the organization representing transplant candidates, recipients, donors and their families and health care professionals. TRIO is a voting member of OPTN/UNOS and has several TRIO members who are now represented on various OPTN/UNOS Committees. We are active members on the Washington DC based “Transplant Roundtable”.

TRIO (Transplant Recipients International Organization) Oklahoma is a non-profit membership organization working to improve the quality of life for transplant recipients, candidates, donor families and others interested in transplant may also join. By sharing personal experiences, chapter members complement the counseling provided by healthcare professionals.

Lorrinda Gray-Davis founded TRIO-Oklahoma Chapter in 2020 and is serving as its first President.
