Rachel recently returned from studying abroad in Israel and is a senior at Harvard University, where she majors in psychology. She is a summer 2007 intern with the Lehman Brothers' asset management group. Rachel said of her Sigma Chi experiences thus far, "It's about a deep-rooted commitment to shared values, a sense of belonging and responsibility, and developing the qualities and skills that make one not only a great leader in the Fraternity, but in every other aspect of life. I have been a part of many organizations, but it is Sigma Chi where the relationships and transformations are lifelong."
