Mark Scott
School Founder

Mark Scott is the founder and owner of Island Montessori. He and his family first moved to Grenada in 2007. Mr. Mark’s two older children had previously attended a Montessori school in the US, and were later home schooled by a Montessori teacher while living in the Bahamas. The family was heartbroken to discover that there was not a Montessori school available in Grenada, and thus decided to establish the Island Montessori school. After over a decade as a primary school, Mr. Mark is very happy to see Island Montessori’s continued growth with the recent addition of our secondary school that allows us to share the Montessori philosophy with even more children around the island.
