Mark Sanchez doesn’t remember every detail from his own prom, but he can recall the important ones. He remembers he went with his best friend, Rebecca. They rented a limousine, as most do, as and they went to a Greek restaurant in Los Angeles beforehand — one that was fancy enough to make the night seem important and special.

Friday evening, Sanchez returned to prom, but this time he was accompanied by more than 100 teenage patients from Children’s Hospital Colorado.

“I still needed help with the boutonnière,” he admitted.

Sanchez was a surprise guest at Children’s 10th annual prom for patients who may have missed their high school proms because of treatments or because they were simply not healthy enough to attend. The event, aptly named “A Night of Champions,” was the first held at Sports Authority Field.

After a few hours of makeup, hairstyling, finger nail-painting, courtesy of local donors, the prom-goers walked a red carpet as cameras flashed. Then they were welcomed inside a fourth-floor suite by Sanchez, who later posed as one of Charlie’s Angeles, donned shutter shades and even Dabbed in photos — all to ensure their memories of prom wouldn’t soon be forgotten.

“I just think it’s important when you’ve been blessed like I have — like any guy on our team has — you’ve got to be a blessing to other people,” Sanchez said. “You’ve got to give back. I didn’t get here on my own. You owe a lot to a lot of other people — people who took time out of their day to come and give you encouragement, to come and help you, to take you to practice and do stuff. This is what that is.”
