Letter from the Principal

Welcome to Triangle Elementary School!  Triangle School is a wonderful learning community that is successful due to the dedication of its staff, the enthusiasm of its students, and the involvement of the parents. As we work together throughout the school year, I am confident we will continue to provide your child with the best learning experience possible.  Our mission is to educate all students to become responsible and productive citizens and lifelong learners. We accomplish this by continuing to instill a love of learning in our students that is focused on a rich tradition of academics, social-emotional learning, the arts, and community building.   

Our primary role is to ensure that superior instruction and learning is taking place in each classroom.  We are also committed to ensuring a safe and orderly environment throughout the school building. The staff works diligently to provide all students opportunities to succeed academically, socially, and through extra-curricular activities. A strong elementary education begins with a strong foundation in reading and math and the Triangle School staff is dedicated to helping make this happen for each and every child. We have a collective responsibility to expose your child to a learning environment that prepares them for their future endeavors. In an effort to accomplish this, we are committed to building relationships between parents, students, and staff, and we look forward to working with each of you to ensure the success of your child.  

I encourage you to become involved in your child’s education.  Please feel welcome to join in the many grade level activities that take place during the year, and please join us at our monthly Home and School meetings.  The Triangle HSA (Home and School Association) meets monthly in the school media center. The Home and School Association sponsors many of our school-wide events, and provides support for many wonderful activities that help make Triangle special! There’s a place for everyone in the Home and School Association!

I am certain that you and your child will enjoy your years with us and we are looking forward to working together as a school community.  Please feel free to call upon us at any time with any questions or concerns you may have.

Together We Shape Our Future at Triangle School!
