Over the last three years, Miller made it her mission to find a kidney donor for Tiffany. She used every resource at her disposal -- Facebook, her friends, and word-of-mouth. What she didn't realize, however, was that the perfect donor was living in her own home.
A few months ago, Miller asked her husband, Chris, if he was willing to see it he was a match for Tiffany's blood type.
"She asked me, 'Do you want to get tested?' I said, 'Sure.' I didn't think anything of it," he told CBS.
According to the Gainesville Times, the Millers haven't stopped there -- they are alsoorganizing a fundraiser to help with Tiffany's post-operation expenses and to provide her and her son a mini-vacation, something they haven’t had in years.
"There are a lot of things that this young girl needs. Yes, she’s getting my husband’s kidney. A lot of people say ‘Why are you doing this? You’re already giving her a kidney.’ Well, we want to make sure this kidney survives. We aren’t giving her this kidney to last today, we’re giving it to her to last a lifetime," Lisa said.
