School Reviews

My son goes to Andrews and loves it. They have small class sizes and fantastic teachers. It is very challenging but awesome to see him grow and learn to reach his potential. They get to be outside a ton too which is great. Also, this website is inaccurate. Tuition is $17k a year and goes through 8th grade.
