Big Brothers Big Sisters is the oldest and largest youth mentoring organization in the United States, having begun nationally in 1904 and locally in 1971. The local Delaware agency is a full affiliated member of the national organization, Big Brothers Big Sisters of America.

Positive long term outcomes with measurable impact are achieved through professionally developed and supported one-to-one mentoring relationships between children and screened and trained volunteer mentors. The agency’s program model is the catalyst to strengthen assets that all children need in their development to become confident, competent and caring adults.
