My son, Clifton, spent one year at Saint Margaret Mary School, and it was an unforgettable experience. From day one, the school embraced him as if he’d been a part of the community for years. The principal, Josh St. Cyr, and his dedicated staff create a warm, family-oriented environment where every child is valued. Key highlights include:

Welcoming Community: Clifton was immediately made to feel at home, fostering a sense of belonging.
Exceptional Leadership: Principal Josh St. Cyr leads with care, ensuring every student feels like part of the family.
Supportive Staff: The teachers and staff go above and beyond to nurture students’ growth.
Christ-Centered Values: The school’s focus on faith and community aligns with its mission to shape compassionate individuals.

As a former Pre-k3 Teacher's Assistant of SMM, I can attest that SMM is a wonderful learning facility for your child. I truly LOVED my job here and looked forward to seeing all of my students each morning... The little ones in our classroom became a part of our family and we all laughed and learned every day! The teachers here WANT to be here and that positive attitude makes a difference in your child's first impression of the many years of upcoming education in their lives. Your child will love SMM and so will you.

We absolutely love this school. My son is treated very well. The teachers are there bc they love their job. My sons class is Pre k (there are 2 teachers in his class) they are wonderful & my son even loves the other teachers. I know bc he talks about the other teachers when he's in the playground. They treat the children well and they learn so much. My son will be there until the 8th grade. (God willing) I give it all 5 stars! Happy mom & dad & happy son makes us a happy family.

St. Margaret Mary Catholic School is a wonderful school! The Teachers, Staff, and Administration are devoted to Catholic education. They focus on developing each child academically and spiritually. My children are loved and treated like family. The education is excellent and technology is used in the classrooms along with a computer class. There are enrichment courses in Art, Library, and PE. Sixth through Eighth grades offers honors classes and an opportunity to earn high school credits for 8th graders. I feel my children are well rounded and ready for high school. SMM is home!

St. Margaret Mary is an awesome catholic school! Both of my boys have been going there since they were in Pre-K and I've never had one complaint about their teachers. The teachers and staff at SMM really care about the health, education and spiritual well being of all their children. I would definitely recommend SMM to a parent wanting to send their child to a great catholic school.

I have two children at SMM currently. I appreciate the teacher's attention to the children's emotional and spiritual needs as well as their academic needs. Additionally, I am so happy with the focus on values and on helping others who are in need. I am very happy with SMM! Go Chargers!

I have been so happy with Saint Margaret Mary. The teachers level of compassion is above par as is the academics and teaching of core values. There is a positive energy running through this school and I feel lucky to be a part of it.
