The longer your child attends this school the more you will appreciate this wonderful community. The parents are welcomed and involved and the staff is committed to each child's success. On top of all this there are motivating and enriching activities, such as a great librarian, the wonderful garden, many field trips, art everywhere, and great test scores. The principal has been there many years and along with the staff and parents, has created something special.
