The school was originally opened as Holy Trinity Episcopal Day School in 1987 and was affiliated with the Episcopal Church. The School was chartered as a regular education school. Initially the school’s purpose was to serve children who needed smaller class sizes. As a result of the small classes, more students with various disabilities attended the school. In 1997, the minister of the church, who was the head of the school, was transferred. The church could no longer fund and support the school. With great success realized by students and families in the program, the parents of the student population assumed the responsibility and created a parent-cooperative based school. The name of the school changed to Trinity School. By 2003, the school was in need of a larger facility to accommodate the increasing student body, and settled into our current location at St. Saviour Church.
In 2005, as part of a strategic planning process, the Board of Trustees of the school decided that the name Trinity School no longer accurately represented who we are. A group of marketing and education professionals volunteered over a period of a year to research and identify a name that would fit our school’s mission and culture. The name Linden Grove School was approved by the board in June of 2006, and the parents voted to accept the new name in August of 2006. At that time, the school became ready to forge ahead with its own identity and resolve the misconception of affiliation between church and school.
