This year's shirt was designed by Four Diamonds child Logan and her brother Gram.
"I THON because I want to do everything in my power to ensure no child or family has to battle cancer alone."
"I find new reasons to THON every day, and that is why I THON."
"It was at this point that I knew I wanted to be apart of something larger than myself and help others fight this cruelsome disease that we call cancer."
"Our families are the embodiment of the Four Diamonds of courage, wisdom, honesty and strength, and they continue to inspire me every day."
