MSAD #51 District Newsletter - June 16, 2025

“My school will amaze you. My school will astound. By far the most fabulous school to be found. Perfectly planned and impeccably clean. On a scale, 1 to 10, it’s more like 15. And learning is fun in a place that’s fun, too. If I built a school, that’s just what I’d do!”
