Welcome to TMI Episcopal! established in 1893, TMI is the Flagship private school of the Episcopal Diocese of West Texas. It is situated in San Antonio between the greater downtown area and the city of Boerne. TMI educates learners in grade levels 6-12 and is the oldest Episcopal Church-sponsored, college-preparatory school in the Southwest. At TMI, we focus on teaching learners in small classroom settings, allowing a great deal of interaction among learners in class and an opportunity to develop close, personal relationships with our faculty members. Our academic community is warm and inviting. We believe that self-esteem is earned through hard work and determination, and we are committed not only to the success of our school, but also to each individual at TMI. All learners who enroll at TMI can choose to attend as a day student, or learners in grade levels 8-12 can enroll in 5-day, 7-day, or flexi-boarding on campus.
