What Parents Say

MMI is an absolutely amazing school. Between the teachers, head of School, dean of students, guidance counselor and everyone else. My only regret is I wish I started my son there in 6th grade so he could’ve experienced it longer. He absolutely loves going to school now. How they prepare them for college and beyond is 2nd to none. I highly recommend MMI.
