M.M.
As a former kidney transplant social worker, I have a few ideas.
1) Contact your transplant coordinator and/or transplant social worker and ask for as much info as possible. The dialysis social worker could be another place to start. Many times they can put you in touch with another family/patient that is willing to share their transplant story.
2) Organ Transplant Support although this is primarily in the Chicagoland area. Maybe they could link you with some organization in your area? www.otsfriends.org
3) National Kidney Foundation www.kidney.org
Best wishes to your mom and aunt.
