Where does the name Old Hall Green come from? 

Old Hall Green is a community in the English countryside between London and Cambridge and home to St Edmund’s College and Prep School. Founded in 1568, St Edmund’s is the oldest Catholic school in England.

The name has personal meaning for Mark and his family: all four of his children attended. The school’s long history reflects qualities we value—faith, perseverance, adaptability, and respect for traditions worth preserving.

Our name and logo bring together the green countryside of Old Hall Green and the rugged beauty of South Dakota’s Badlands, representing global experience grounded in local understanding.
