My daughter has been at STM since kindergarten and is now in 5th grade. I could not be happier with the school, teachers, or academics. It truly is a joyful learning community and my daughter has thrived there the last few years - she is challenged academically and spiritually. They value giving to the community and those in need and this strong moral compass has been instilled in large part due to the school's teachings and actions. Academically she excels (according to her grades and state testing), excels at math, is well spoken and articulate, and motivated to learn.

STM is a wonderful school! The teachers are top-notch and help to make learning joyful and appropriately challenging. Children are taught to be caring about others, not only through words but through service activities like class projects. God is at the center of each day. My child is excited to go to school each day, which is the best confirmation of the great sense of community at the school!

My son began his journey at Saint Thomas More as a Kindergartner in 2019 and has excelled tremendously. The curriculum is designed to challenge the children to reach their full potential. The one-on-one interaction between the teacher and students is critical in order to truly assess the needs and academic level of each child. My son loves his school community and vows to be a student who will complete all grade levels at STM. He longs to be an 8th-grade buddy to a kindergartener one day and teach them the ropes of STM. His confidence and self-esteem are at an all-time high. At STM, my son is receiving the Catholic foundation I received as a child, which is reinforcing the morals and values I am instilling in him. I couldn`t ask for a better school for my son to attend. Go Tigers!

We joined the STM Community in July 2019 due to its nice reputation and size. Since then, our expectations are exceeded regularly and we are so happy about our decision. Our daughters assimilated quickly and effectively into the primary school and truly look forward to going to school [almost] every day; they're learning and having fun doing it. The other families are incredibly welcoming, warm, and generous with their time-and we've already made some great new friends. The staff and faculty offer a wide range of diverse experience and backgrounds, and are led by a kind, yet fair Principal. This is evident in their focused and operative response to the pandemic, inclusive of the daily welcoming (and temp checks) by faculty at drop off and organized send off at pick up. The teachers are passionate about their jobs and the students and engage collaboratively with parents. The school disrupts any opportunity for monotony with regular spirit days, celebrations, and other activities. One of the best elements of the community is the down-to-earth nature and proclivity for authenticity; we haven`t experienced any ulterior or self-seeking agendas. We highly recommend this school to any prospective families.

STM is a school that provides challenging academics in a nurturing environment. It is a supportive community. The children are taught to be responsible for themselves. I find the students joyful and adept at public speaking; which I find to be an important skill as they move on to high school.
