Rachel Joy Scott was the first victim during the Columbine High School shooting in 1999.
"Rachel's father shortly after that realized that he wanted to keep Rachel's goal going, start a chain reaction of kindness and compassion," said J.B. Braden, Speaker for Rachel's Challenge.
Rachel's message of kindness is now being spread to schools across the country through guest speakers.
"The amount of people I've seen come up to me and tell me the difference it's made in their lives and the changes they've made," Braden said.
Braden was the speaker at Aberdeen Central today, he recalls stories from students he's spoken with over the years.
"This young girl she stood up during the training, and she shared how it impacted her, but she also shared with her classmates how she tried to commit suicide several times, and she said now I feel I have something to live for," Braden said.
But Rachel's Challenge doesn't stop after the speech.
"I get to work really closely with some wonderful students and being able to spread this message of kindness and compassion with them and watch them be able to spread it to other students is very meaningful to me," said Saundra Anderson, Friends of Rachel Club Adviser.
Aberdeen Central is one of many schools who have formed the Friends of Rachel Club.
"We've been working on some service projects, there's been a few times throughout the year that we've put locker signs up on student lockers, we just put up some for Valentines Day yesterday," Anderson said.
The club's goal is to continue spreading the message of kindness long after speaker Braden leaves.
"We're trying to instill something that's long term, and that's to make a difference, to be kind to other people, and to make a difference, and to treat people well," said Aberdeen Central High School Principal Dr. Jason Uttermark.
