Kidney disease is a critical women's health issue, which is why the Phi Sigma Sigma Foundation supports the National Kidney Foundation as our primary philanthropic endeavor. Since our selection of the NKF in 1971, we have donated hundreds of thousands of dollars to this voluntary organization. With Phi Sigma Sigma Foundation funding, the NKF has produced educational literature and media presentations, supported summer camps for children affected with kidney disease, and funded medical research.
