St. Thomas More School is an accredited COED college preparatory school for students who have demonstrated intellectual ability but who have not yet realized their potential.
Within a structured environment, we strive to motivate, nurture, and strengthen the intellectual, moral, physical, and social development of every student.
Dedicated faculty, individualized attention, small classes, challenging yet fun athletics and extracurricular activities, in a 100% boarding environment, are the cornerstones of an STM education.
Our robust Summer@STM program combines academics, study skills, athletics, and recreational activities, to ensure that students have a fun & memorable summer and are in a better position to achieve their goals when they return to school in the fall.
