School Reviews

Mission did a great job at preparing me for university and even graduate school. My years at MCP taught me more than standard academic knowledge but prepared me how to manage time, study in an efficient manner and involve myself in a community. I was involved with sports, yearbook, student government and various other clubs. Mission did a great job of instilling a sense of community in all of their activities, even those which took place after school. Everyone was encouraged to do well academically and in extra curricular activities. During my attendance, it was viewed as "cool" to do well in school. Other students and friends pushed each other to do well academically. The teachers and community at Mission were always extremely supportive and welcoming during my time as a student. They wanted all of their students to succeed and were always available for questions/help after school. I would highly recommend Mission to anyone considering attending or sending their child.
