• Belonging, in which we foster a culture of respect, well‑being, and connection that values all individuals and empowers them to discover and be their authentic selves.
• Kindness, in which we strengthen our communities by recognizing our common humanity and treating ourselves and others with respect and compassion.

The vibrancy and vitality we feel in the classrooms, hallways, stages, and playing fields of BB&N derive from the people who are here.
