Cantwell-Sacred Heart of Mary High School (CSHM) was formed in 1991 through the merger of two historic schools—Cantwell High School for young men (est. 1946) and Sacred Heart of Mary High School for young women (est. 1942). Together, they built a lasting legacy of academic excellence, faith, and service.

Our alumni are a vital part of this legacy—giving back as mentors, educators, and supporters of scholarships and school programs. Their generosity helps shape the future for today’s Cardinals.
