We believe that each child is unique. We have created a school environment that is safe, secure, and that addresses the needs of all students. In addition to our strong academic programs that challenge students and provide them with a solid foundation for learning, we stress the development of social skills that encourage confidence, self-esteem and healthy interactions with others.


We have high standards for our students. We want them to have the skills to be successful in society, and also the humanity to contribute to an improved world. Please join in a partnership with us as we work toward these important goals.  We strive for an excellent relationship among children, parents and teachers working together to make each year a success.
