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."

😴Last weekend, the third years experienced something quite extraordinary; they not only had the whole school to themselves, but they also got to spend the night. The kids, along with a few chaperones and their teachers, had a fun-filled evening. They participated in activities, played games, and even gazed at the stars. 🏫🌙 #MSSA #themontessorischoolofsanantonio ... See MoreSee Less
