School Reviews

My daughter is in her third year at Montessori Family School, now in her 1st Year of Lower Elementary. The staff clearly cares very much about the students and there is a strong focus on developing the strengths of each individual child. While they are offering a great outdoor schooling option this year, we chose the more conservative Year-at-Home online option. It`s a very small class size with an excellent teacher:student ratio and we have seen our daughter's learning and development grow much stronger already this school year. The individualized approach to learning works well and she is excelling in math and language as a result. They have added in cursive to her curriculum and the students have been preparing and sharing presentations every week on a variety of topics - all wonderful to witness as a parent. During such a challenging time, it's very reassuring to know that her learning environment is solid and steady.
