My girls love this school and jump out of the car each morning excited to see their teachers and friends. AIS has the perfect balance of a nurturing environment and excellent education.

I have a few daughters at this school and am constantly amazed at the warmth and endless support from the faculty. Each teacher goes above and beyond to help educate my girls in the best way possible to their individual needs and learning styles. I see my girls developing into intelligent, kind, mindful, thoughtful and happy girls. I attribute this development to this amazing school.
