In the fall of 1934, St. Gertrude School opened its doors for the first time, admitting forty children in grades 1 through 8. The school building consisted of three classrooms on the first floor, a convent on the second, and a basement. Three Sisters from St. Cecilia Congregation of Dominican Sisters in Nashville, Tennessee were sent to oversee the education of the children. Sister Sebastian was the first principal.

By 1945, following the end of World War II, enrollment had increased to 117, and the school began to experience the first signs of growing pains. To remedy the situation, a decision was made to convert a portion of the school basement to a classroom, allowing for a total of four classrooms. By 1949 enrollment had increased to 220 and was rising steadily. This necessitated the addition of three classrooms on the first floor, a cafeteria and restrooms in the basement, and increased living quarters for the additional sisters needed to staff the school. By 1955, enrollment had climbed to 505, and once again the walls began to bulge. To alleviate the overcrowding and allow for continued growth, a second addition was built containing a connecting basement and four classrooms. In 1958, the final addition of the four classrooms in the back of the school was added.

Since the opening of the school in 1934, a Dominican Sister from St. Cecilia Congregation in Nashville has served as principal of the school. Presently, there are also three Dominican sisters on the teaching staff, along with very qualified and experienced lay faculty.

In August of 2006, St. Gertrude's 72 year old building was torn down and a brand new school building opened wide it's doors . This multi-million dollar project is a testimony to the zeal of the parishioners for the children of St. Gertrude and to the vibrancy of the parish and school community.

Presently, there are 2 classes of grades 1st-8th grade. There is a morning, afternoon and full day kindergarten as well as a morning, afternoon and full day pre-kindergarten. The new school was intentionally designed to not hold more students than this so as to maintain its family atmosphere.

The commitment of parents and parishioners to various volunteer activities continues to provide a spirit of community within the school. This spirit helps to give St. Gertrude School a solid foundation upon which to continue its academic excellence in the Dominican tradition.
