If you''re looking for a safe, caring, nurturing, diverse and great learning environment for your child, I''d strongly suggest taking a close look at St. Mark School in Catonsville, Maryland. Me and my 2 brothers went there and we loved it and now I have 2 boys who attend and we''ve been incredibly pleased with the school and the teachers. The community is even better. Our boys spent some time in the preschool before starting kindergarten and immediately felt comfortable. We loved Mrs. Masters and the teachers in preschool so much! We have also been very active in the athletic program through the school with everything from soccer to basketball. The programs are fun, encouraging and great for the kids and parents. It's a fantastic place. Highly Recommend!!!

St. Mark is an academically and spiritually strong school. Both my children went on to private high schools, and in speaking to their advisers this is what they said. To them, St. Mark is the benchmark of academic preparation for high school. They look forward to welcoming St. Mark students to their schools. This speaks volumes as to the strength of both the lower and middle schools. You''ll be glad you sent your child to St. Mark!

Great school! Faculty and Teachers truly care about the whole life and education of the children. Many experienced and engaging teachers keep children interested, focused, and make learning fun. Great math, science, and reading/english/literature teachers and programs. The Catholic nature of the school helps our children feel safe at school, keeps learning wholesome and friendly, and helps filter-out some of the cultural craziness that cannot be filtered-out at public schools, while still keeping the curriculum up-to-date with modern science and current events. Tons of parental, family, and parishioner involvement make this parish school feel like one big family. Many of the teachers were once students at St. Mark, have children that are either alumni or current students, and a few have soon to be students, making the teachers highly invested in the educational quality and overall enviroment of the school. An involved home-school association keeps parents a say in the schools daily events. The online resources, such as "power school" help parents track their students daily progress and classroom performance. Siblings discounts make it affordable for large families.
