Join the fun this summer at Camp MSSA! Enrollment is now open for a variety of exciting weekly themed sessions, including sports, STEM, recreation, music, chess, and art.
Welcome to The Montessori School of San Antonio
Where children are guided to be passionate learners, independent thinkers, and engaged citizens.
The Montessori School of San Antonio was founded as the Judson School – a Montessori Workshop in 1974. From there it has grown to include Primary, Elementary, and Middle School Montessori programs. The MSSA campus is a secure 24-acre parcel at the intersection of Loop 1604 and Rogers Ranch Parkway in far North-Central San Antonio with a surrounding environment designed specifically to meet the learning criteria set out by Dr. Maria Montessori.
As a parent, I can confidently say that I could not have chosen a better community for my children and our family unit. MSSA works hard to maintain a wonderful learning environment where grace and courtesy are always paramount. The education is challenging, yet manageable, and it allows students to have a very subtle transition when moving on to a higher grade-level."

Our Lower Elementary students took the stage in an engaging Reader's Theater performance, bringing science to life through drama! 🎤📚
From wild weather patterns to rocky adventures beneath our feet, soaring through the solar system, and exploring animal adaptations, each scene was packed with knowledge, creativity, and confidence. 🌪🌋🚀🐾 Bravo to the students and teachers. The performances were great! #mssa #themontessorischoolofsanantonio #readerstheater
