    "My absolute favorite Dana Hall memory of all time is winning the EIL Championship for tennis! Dana Hall Varsity Tennis faced our toughest rival for our last match. Everyone was watching that match; I remember the moment when I won my match and the whole team came out running and screaming onto the court. We were all hugging and smiling at each other. I was so proud to be a Dana Hall student-athlete."
