Community Feedback
“We moved from Denver to Littleton at the beginning of the school year. Our boys are in 4th and 6th grade. Everyone has been so welcoming, helpful and kind! It is obvious that the teachers and staff are there because it is their passion. The education they are receiving is top notch. We are so happy with St Mary’s!”
“Our family has been incredibly blessed to have all 5 of our children at St Mary of Littleton! We have been members of the school community for the past 9 years. St Mary has been more than a school to us- it is our family- a unique community dedicated to intertwining excellence in education with virtue by raising our children to become saints! St Mary strives to incorporate faith into all the curriculum while truly exemplifying truth, beauty and goodness.”
“Incredibly grateful to be a part of this school. The teachers really care about the success of the students. There is strive for not only academic excellence but more importantly creating well rounded human beings. Each grade focuses on a virtue that they put into practice in the classroom or in assignments at home. For example, my 4th grader is learning the virtue of Temperance through the practice of planning a brunch party in the classroom. The fellowship among the families, the priests and the teachers is an added bonus. ”
