Parking is a major issue, as is the traffic over there. It's a shame they don't have their own parking lot of some kind. However, the excellence, kindness and dedication of the teachers is wonderful. Our 5 year old son adores his teacher Miss Andrade, and she is wonderful with all of her kids. Majority of students seem happy to be at school.

This is a very nice school except for 1 thing: bullying. I understand that they have 0 tolerance for bullying but it is still happening. It happens to me all the time. Make sure to believe your child though if there is bullies there, because there are. I have been bullied by people that are younger than me, so just remember that bullies can come in all shapes and sizes. Everything else is perfect. We have big classrooms, a large cafeteria, and all my special teachers have their own rooms. Also, all the cite leaders have their own offices. They even have improved water fillers where you put your water bottle onto a small platform and water pours into it!
