Growing up, Calvert School student Oliver C. didn’t realize right away that his older sister, Sutton, had special needs. He only understood that she was special to him. Sutton was born prematurely and contracted meningitis at six weeks old, sustaining a brain injury because of it. She is 12 years old now and attends the Baltimore Lab School. In honor of Sutton, Oliver began participating in the Polar Bear Plunge when he was five years old with his grandfather. Since then, his team has expanded to include other friends and family members.
