Believing deeply in inclusion she fought for her son to be educated in the mainstream. Witnessing the fear this challenge created in mainstream teachers, Marion decided to develop a specialism in teaching such children. At first she got paid by working privately for parents whose children were at home, or who needed an advisory teacher to support an inclusive placement. Eventually there were enough clients that she was able to start her own organisation, CASTLE: Communicative and Supportive Teaching / Learning Environment. As CASTLE became established it became easier for Marion to fund CASTLE services through LEAs and schools rather than individual parents.
