Together We Shine
School psychologists partner with families, teachers, school administrators, and other professionals to create safe, healthy, and supportive learning environments that strengthen connections between home, school, and the community. They apply expertise in mental health, learning, and behavior to help children and youth succeed academically, socially, behaviorally, and emotionally. They are also important members of school safety and crisis teams.
We, the school psychologists at Derry Township School District, thank you our parents, community, staff and administration for the opportunity to work with such amazing students!
