Diverse, tight-knit community opens a world of opportunity

Students come to us from across the United States and around the globe. While many graduates are admitted to the five military service academies, most advance to the colleges, universities, and professional schools of their choice.

Structured, supportive environment builds character and confidence

Traditional college prep education at St. John’s Northwestern is structured around our four pillars: academics, athletics and wellness, leadership growth, and spiritual and character development. Boys and girls are guided to look within and discover their unique strengths, learning to lead and inspire others by their own example.
