Vision...one of our most precious senses. Unexplainable to those without it; irreplaceable to those who have it. Protecting the gift of sight is one of Delta Gamma's highest priorities. Since 1936, Delta Gamma's philanthropic purpose has been to stop blindness before it starts. For men and women for whom blindness is a fact, the mission has been to impact the quality of their lives in a myriad of positive ways.
