"I wanted to do something she wouldn't expect, something where she wouldn't have the slightest clue, something special, and of course something meaningful to her," he told INSIDE EDITION, "And there's nothing that means more to her than her job as a teacher and her kids."
He spent three months planning the proposal and putting together a nearly ten-minute video featuring family, friends and co-workers, with all of them telling her to "Say yes!"
Justin had Mandy summoned to the principal's office for a meeting, so that her 42 fourth-grade students and fellow teachers could gather in herclassroom for the big moment. When the proposal video was done Justin walked in and got down on one knee.
"She was shocked! Absolutely clueless! She noticed both of my brothers and one of their girlfriends in the back of her class and she didn't know if I was going to pop out of one of her cabinets," he said.
"When I came in with a few of her previous students, I believe it was the biggest I have ever seen her smile. It was all worthwhile!"
The pair is planning to get married in October 2016.
