I received a very solid education from this school. I began attending in JK (Junior Kindergarten) and graduated after 14 years there. Now that I''m in college, I can look back and say MICDS prepared me incredibly well for the challenges I''m beginning to face. I grew up in a school that exposed me to different cultures, gave me incredible opportunities to grow, and had teachers that were flexible and excited to teach every day. And on top of that, they don't accept anything less than your best. I was challenged constantly and, despite being shy, never felt like my opinion was unwelcome. I found my voice at MICDS and I would highly recommend it to anyone searching for a private school in St. Louis who wants a school focused on community and excellence.

Could not have had a better education. Sailed through the SATs to enter an Ivy League college. French started in 3rd grade. Gym was great with all the calisthenics and equipment. Mr. Beasley was our headmaster! Class of 1950!! Yes... you read that right.
