Welcome to Martensdale-St. Marys Junior/Senior High School!

At Martensdale-St. Marys Junior/Senior High School, we believe there is something truly special about being a Blue Devil—a deep sense of pride, connection, and shared commitment that unites students, staff, families, and the broader community. We are more than a school—we are a family that supports one another in and out of the classroom, celebrating achievements, navigating challenges, and growing together.

From the cafeteria to the classroom, from the stage to competition, you'll find a culture of care and excellence that sets MSTM apart. Our size enables personalized learning, fosters meaningful relationships, and cultivates a strong sense of belonging, while still offering exceptional programs and opportunities.
