Tia Wimbush and Susan Ellis have been co-workers for a decade, and while they didn't know each other well, they learned two years ago that their spouses each needed a kidney transplant. Then ... something remarkable happened. The women saw each other in a restroom at work and started chatting as they washed their hands. They had a lot in common, both working in information technology at Children's Healthcare of Atlanta and dealing with the same medical stress at home. Neither was a match to be an organ donor for her own husband, and the transplant waiting lists are impossibly long. Wimbush casually asked Ellis what her husband's blood type was. He's type O, Ellis replied. Wimbush said her husband was type AB. The women paused for a moment and looked at each other. Then Wimbush realized they might have stumbled upon something that might help save both of their husbands' lives. Wimbush thought she might be a match for Ellis's husband, and incredibly " she thought Ellis could be a match for her husband. Antibody tests revealed that each woman was an excellent match for the other's spouse. So in March, seven months after that chance conversation, Wimbush donated one of her kidneys to Lance Ellis, 41, and Susan Ellis donated one of hers to Rodney Wimbush, 45. Both transplants done at Piedmont Atlanta Hospital went so well that the men have almost fully recovered and are going on weekend hikes with friends and family, Tia Wimbush said.
