In 1919, the local sorority Delta Pi was organized by Hazel Ross and then National President Irene Patchett Smith who had come to the campus to form a local with the sole intention of petitioning Alpha Delta Pi. In 1925, national officers and members of Alpha Chi from UCLA installed the group as Alpha Psi chapter. In 1940, the chapter purchased a large home on the corner of sorority and fraternity row. The house was affectionately called "the house that dimes built" because collegians and alumnae had collected change in blue and white banks labeled with Alpha Delta Pi to purchase the house. The house and its grounds have been featured in several movies. Two great-granddaughters of Founder Octavia Andrew Rush, Mary Ann Rush Medler and Lettye Maye Rush, were initiated into Alpha Psi and have been involved with the sorority throughout their lives. Kristen Von Kleinsmid is a long-serving advisor and former Foundation Trustee Melissa DeMotte also has a long record of service.
