The Seneca Middle School community will foster the intellectual, emotional, and physical growth of every child
by developing a positive self-image, a strong desire for learning, and a sense of respect for self and others.
We will accomplish this by providing a challenging curriculum in a safe and supportive atmosphere,
as our children mature into productive citizens.
