Bluffton Icon founder Fred Steiner has a story about Forgotten Bluffton that reveals the Diller country school at 7370 Grismore Road had some exceptional graduates.

"The Diller country school in northwest Richland Township had two rooms, which was unusual for country schools. But, it was most famous for the fact that from six to 10 of its graduates entered the medical profession."
