The Caitlin Raymond International Registry (CRIR), is a non profit organization of the UMass Memorial Medical Center in Massachusetts. CRIR was originally established in 1986 as a unit within the Division of Hematology-Oncology of the Department of Pediatrics at the University of Massachusetts Medical Center specifically as a coordinating center for conducting national and international searches for unrelated donors. Today, approximately 300 patients each month are submitted for search by physicians from all over the world.
CRIR also operates an unrelated stem cell donor registry, accessible to search coordinating centers worldwide. Able to coordinate volunteer donor registration drives throughout the United States, CRIR works with both private and public recruitment groups to educate potential donors and increase the available donor panel.
