Choosing ICGS for our daughters education was the best decision we have made as a family. The teachers and administration is top notch. My child has learned respect, compassion, faith, leadership along with an excellent education. IC is a family that we are proud to be part of.

ICGS was the best investment we have ever made. Along with excellent academics, our 3 children received an excellent faith foundation with an emphasis on Catholic leadership. They left the school with a solid sense of confidence along with a sense of their responsibility to make our world a better place. Each of them were well prepared in self-discipline and time management. As a result they have excelled in high school in the classroom, in athletics, and in extracurricular activities. This foundation was instrumental in providing them with excellent choices for college. We can't recommend this school highly enough.
