Our Promise

A leader in modular construction, American Modular Systems is transforming the way schools, classrooms and buildings are constructed.

At AMS, we’re transforming the way schools are built and redefining the standards for how they perform, delivering superior quality quickly and cost-effectively, while giving every customer an exceptional experience from start to finish. That’s not just our advantage—it’s our promise.

Our modular buildings are permanent structures—an affordable alternative to portable, relocatable and temporary schools, classrooms and buildings. Every AMS modular school building is DSA pre-approved, providing a healthy, comfortable learning environment precison-built to your exact needs and budget.
