Sigma Pi is devoted to serving the Duke community as well as the local Durham community and local philanthropies in the state of North Carolina. Sigma Pi at Duke University officially supports Carolina Tiger Rescue, a nonprofit wildlife sanctuary dedicated to saving and protecting wild cats in captivity and in the wild. The brothers of Sigma Pi successfully adopted Nitro, a 13-year-old blind tiger who merrily chuffles at his guests. Aside from contributing to Carolina Tiger Rescue, Duke Sigma Pi also devotes time to other organizations such as Habitat for Humanity and Wags 4 Tags. Additionally, the Iota Xi Chapter supports the national philanthropy of Sigma Pi, the Sean Vernon Feliciano Amazing Day Foundation.
