Paula Cordova found out Clifton Vannorsdall needed a new kidney when her co-worker mentioned it in passing.

ESCALON, Calif. — Clifton Vannorsdall has been battling stage 3 kidney disease since 2014. Both of his kidneys are bad, and they don't appear to be getting better on their own. The 46-year-old's health has been declining ever since.

Vannorsdall is talking about Paula Cordova, a Manteca mother of four, and the aforementioned coworker of Vannorsdall's oldest daughter, Samantha

Cordova signed up the day she found out what Vannorsdall needed to survive, just moments after his daughter mentioned they were looking into putting him on a waiting list for a new kidney.

Paula got the idea after watching American Ninja Warrior a few months earlier. A contestant on the popular game show donated a kidney to his friend and was still able to compete months later.

“So I told myself, if that ever crosses my radar, I’m going to do it," Cordova said.

They’re planning to do their surgeries sometime in July.

“Even though I gave her a hug and told her thank you, but I still don’t know how to repay it,” Vannorsdall said. “Just live a happy life, that’s all I can do and I thank her for it."
