This school is such a little gem. Located just across the street from the Gulf of Mexico, we couldn't believe how lucky we were to have found such an awesome school for our son. Miss Katie and Miss Kathy are excellent teachers who truly take their time to work with your child and his/her individual needs. We have almost completed their primary program and will move on to lower elementary in August. They also have a great beach summer camp for 3-6-year-olds that you don't want to miss!
