The 16-year-old, who suffers with muscular dystrophy, thought he was going to hospital for treatment but instead his car pulled up outside the training ground of Manchester United Football Club.
Brandon, who studies computer and game design at Telford College of Art of Technology, spent last Monday meeting the players, including Wayne Rooney and Chris Smalling, managers and staff.
And it was all thanks to national charity Muscle Help Foundation.
His aunt Becky Kinsey nominated him for the opportunity and one of the charity's Muscle Warriors organised the day to make Brandon's dreams come true.
Brandon's mother Amanda, who lives with her family in Grange Close, Stirchley, said her son had an "absolutely fantastic" day.
She said: "We told him he had a hospital appointment in Manchester but then took him to the training ground.
"All the players greeted him, he met the manager and had something to eat. It was brilliant, it was a dream come true for Brandon as he's a huge Man United fan. He then was taken round the museum there."
Brandon went to Alder Hey Children's Hospital in Liverpool three years ago for a major operation when a rod was put in his back.
He regularly visits Hope House for respite care, both with his family and sometimes for an independent stay. He first started going to Hope House shortly after he was diagnosed at the age of four.
His aunt Becky added: "The muscle warrior from the charity drove all the way from London to come to the day, they were fantastic. We just want everyone to know what a great charity it is."
