banner below the shield are the words in Greek of the sorority's open motto, "Faithful Unto Death". Adopted in 1903, the badge of the sorority is an equilateral gold triangle bordered with pearls, with a small semi circular indentation on each side. On the gold triangle is a raised black enamel triangle bearing a gold sigma in each corner. In the center of the badge is another symbol of the sorority, a skull and crossbones. Philanthropy The Sigma Sigma Sigma Foundation is a non-profit corporation formed in 1992. It distributes funds for charitable, educational, and miscellaneous purposes, including programs that support women's leadership, student grants and scholarships, and play therapy programs for hospitalized children. The organization centers its latter philanthropic efforts around the theme “Sigma Serves Children,” specifically through the Robbie Page Memorial (RPM). On September 15, 1951, Robbie Page, the son of Tri Sigma's National President, died of bulbar polio, a disease which at that time had no cure or vaccine; this death prompted his parents to establish a memorial fund in his honor. The sorority adopted this fund as its official philanthropy in 1954. In its early years, the RPM supported various polio research projects, including the Salk vaccine trials. It now focuses on supporting play therapy for hospitalized children and providing support for playrooms, libraries, and programs for children undergoing long-term hospital care. Current national efforts are centered in funding fellowships at the Children's Medical Center in Dallas, Texas, and in funding graduate assistantships at the University of North Carolina Hospitals in Chapel Hill, North Carolina. At UNC, the sorority also funds the Robbie Page Play Atrium. The National Therapeutic Recreation Society has recognized Sigma Sigma Sigma for their support of Child Life and Play Therapy Programs. In 2016, Sigma Sigma Sigma added the March of Dimes as a national philanthropic partner. Membership National Headquarters Tri Sigma's National Memorial Headquarters is located in Woodstock, Virginia at the Mabel Lee Walton House, a historical landmark. Named after the sorority's third National President, the Walton House serves as the main operations center of Tri Sigma, where day-to-day business is conducted. The sorority acquired the house in 1963; the contributions of individual members, and the dues and fees of alumnae and collegiate chapters, helped to purchase and furnish the property and to maintain it still.
