Sixteen years ago, Dr. Keith Nisbett and his wife, Kim, didn’t set out to create an entrenched artistic home for amateur actors across south-central Missouri. As homeschool parents, they simply wanted to provide eldest daughter Amy, then a teenager, with the opportunity to perform on stage.That first show — From the Mixed-Up Files of Mrs. Basil E. Frankweiler, an adaptation of a popular children’s book — quickly became a full-fledged production. And as the nonprofit theater has laid down roots in Rolla, it’s evolved from a Nisbett family affair into a full-fledged community theater, with a healthy dose of participation by Missouri S&T students, staff, other faculty members and the community.
