The Quaker belief that there is "that of God" in each of us shapes everything we do at Sidwell Friends School. It inspires us to show kindness and respect toward one another. It motivates us to recognize and nurture each person's unique gifts. It teaches us to apply our talents in service to others and to work courageously for peace.
Unlike many other Friends schools, Sidwell Friends School has never been "under the care of a Meeting." Its Quaker character has been the product of vital Quaker leadership—in the beginning from the School's founder Thomas Sidwell, and in recent years from Quaker Heads of School Robert Smith, Earl Harrison, Bruce Stewart, and Tom Farquhar. This leadership has also come from the Board of Trustees, more than half of whose members are Quakers.
