Rocky Boy High School Class of 2023 Valedictorian Kellen Ryder Colliflower speaks Thursday evening in the high school gymnasium to his fellow graduates at the school's graduation ceremony. Colliflower thanked his fellow students along with many teachers for staying by his side through difficult times. While their paths may diverge as this part of their lives ends, he said, they will always have the experiences of being together. "After all the challenges, you have made it," he said. "You've shown what determination and perseverance looks like."
