MY KIDS LOVE THIS SCHOOL
5 10/10/2025
My child had a successful 6 years (kindergarten~5th grade) at this school. All of the activities, staff members, and principal Mr. Robert Sileo had to offer was extravagant. This school had everything I wanted for my child. The school buildings were reconstructed which turned out excellent will clean bathrooms to new Smartboads. The art festivials and winter/spring concerts were entertaining as well as the annual ice cream social which everyone loves to be at school for. The teachers were all extremely nice and full of knowledge. I think this school has no limit for excellence and learning. I would definitely without a doubt recommend this school to a parent whom is looking for a school for his/her child. But I am worried about the middle school in this area.
