“The progress our son Christopher has made at Cornerstone is astonishing. Ms. Lee focuses on the whole child and really encourages Christopher to love learning and to respect others as well as himself. In just four months we've some amazing changes. He's only three and learning to read and write. More importantly he's becoming more aware of the effect his actions have on the outside world and is increasingly compassionate.”
