As the music started, and Heather walked out, a man helped Ralph out of his chair. Ralph walked over and took Heather's hand.
What followed was something beautiful. Heather's look of joy was precious.
"When she grabbed my hand I sort of felt safe and walked down," Ralph Duquette told ABC News. "It was so amazing, she was so happy. It was something that every father dreams of."
The only people who had known about the plan were Ralph, the DJ, the caretaker and the physical therapist.
Ralph stumbled a bit as walked with her, but with Heather's support, he made it down the aisle. He said it was something he had been wanting since Heather was engaged in August, and something he had been working on since April.
For Heather and her now husband, Dan Casoria, this day would have been memorable no matter what, but Ralph made it even more beautiful.
