A dispatcher at a Florida sheriff’s office has given her colleague the best Christmas present ever: a new kidney.

Amber Savoie, a dispatcher for the Palm Beach County Sheriff’s Office, earlier this month donated a kidney to Jesse Mesa, a fellow dispatcher who was diagnosed with Lupus.

After a potential donor dropped out this year, Jesse made a last-ditch effort by sending out an email to the entire Palm Beach County Sheriff’s Office, asking if someone might consider helping her.

Even though Amber didn’t know her colleague well, she volunteered. Jesse works the night shift while Jesse works during the day.

Amber said she knew her colleague had children — ages 19 and 12 — and she wanted Jesse to be able to watch them grow up.

“She’s completely unselfish and an amazing human being,” said Jesse..
