Tami Martin-Dietrich was left paralyzed from the waist down following a car crash in 1999.
But on her wedding day, the paraplegic bride-to-be stood up, and walked down the aisle.
With a gait trainer tucked under her white gown, the 44-year-old defied her doctors and walked the 69 feet to her teary-eyed fiancé, Rob Martin-Dietrich, at Disney World's Wedding Pavilion in Florida.
And it wasn't her only incredible achievement, she also managed to lose around 192lbs (85kg) gained from inactivity, in time for the wedding, despite being wheelchair-bound.
Speaking to DailyMail.com, Tami described the moment she stunned guests by walking down the aisle on September 6 - the first time she has walked in public in 15 years, as 'magical'.
'I had always wanted to walk down the aisle, but I'd been told I would never walk again. At first, I thought I would just stand up to say my vows. But on the day, I thought, "I'm going to do this".
'I'd done three weeks of intense physical therapy, and the therapists had helped me to stand up and take a few steps. But none of them were available on the day of the wedding.'
'So I put my faith in God and walked 69 feet in public for the first time. It was a magical experience. To say that for 15 years I hadn't been able to walk and then I was walking down the aisle toward Rob.'
Strength-building: The 44-year-old went through hours of grueling therapy sessions and slowly the pounds slipped away.
These include zumba classes, scuba diving, dancing, supplements, determination and the support of her groom-to-be, who is a specialist in nutrition, and therefore 'knows how to eat healthily'.
Describing the moment he saw his future wife walk down the aisle, the 45-year-old added: 'It was amazing. There was a lot of pressure on Tami and she was incredible.'
'Seeing her come through the doors and walk toward me was just amazing.'
