An Ohio girl is recovering after getting a critical kidney transplant — with the organ donated by her former kindergarten teacher.

Nicole Miller — an 8-year-old first-grader at Mansfield Christian School — got the kidney last week from Wendy Killian, who was her kindergarten teacher last year.

Nicole suffered from a genetic disorder that caused kidney malformation.

Killian became involved during a parent-teacher conference with Nicole’s mother. The teacher asked for the criteria needed to be a donor and found she met them. She says she was inspired to be a donor because her son needed and received a blood platelet transfusion.

The transplant happened last Tuesday at Rainbow Babies and Children’s Hospital in Cleveland.
