Mill Springs Academy was started in 1981 when Tweetie L. Moore (pictured) founded the school that was to become the destination for hundreds of children. It was called The New School and was housed in the Sandy Springs home and art studio of Ed Dodd, creator of the Mark Trail comic strip. Tweetie assembled a team of talented teachers who knew how to create a safe environment for children whose unique learning styles could not be met in traditional public or private schools. The school provided each child with opportunities to learn and to grow academically, socially and emotionally. Students came to understand their responsibilities as learners and as members of their classrooms and school communities. Children succeeded in this school ... many for the first time in their lives!
In 1997, Mill Springs Academy moved to its current 85-acre campus on New Providence Road in Alpharetta after a devastating fire destroyed a major part of its former campus in Sandy Springs. The school benefited greatly from the support of faculty, parents, students, advisors and community leaders working together to expedite the move to the new campus. Six temporary buildings were constructed as learning spaces for the school's 135 students. In 1999 Mill Springs completed construction of the Tweetie Lewis Moore Student Activities Center, the first permanent facility on the new campus.
