The Stanley Jon Odlum Memorial Secondary School was established in September 2017. The school compound, located at Marigot, was the home of the Marigot Secondary School (renamed to the Jon Odlum Secondary School in March 2016) from 2006-2017. Due to extenuating circumstances, George Charles Secondary School was temporarily housed at the Marigot Secondary School in September 2016. Both schools were run independently and shared the physical school compound. In July 2017, both Jon Odlum Secondary and George Charles Secondary were decommissioned and students and staff were merged to form a new secondary school; The Stanley Jon Odlum Memorial Secondary School.
The school is named after Stanley Nicholas Jon Odlum (9 May 1936 – 19 February 2013) a famous Saint Lucian politician, writer, sports enthusiast and social activist.
The current Principal is Mrs Cleopatra Fitz. and the Vice Principal is Mr Shari Girard.
