Our Badge
Our badge was carefully designed to reflect upon our values. Reflecting on our values, Lady Justice is blind-folded. She is blind-folded to symbolize justice shall be viewed in an impartial manner. The scale indicates equal justice for all. The sword is a symbol of power of our American justice system. On the third ribbon are the words “Scientia Est Potentia.” In Latin the words translate to “Knowledge by itself is power.” Indeed, we agree the more knowledge we have, the more we are inclined to empower ourselves to make a difference in our lives and the lives of others.
