In late May 2021, Alpha Phi was invited to be the third sorority on campus. Alpha Phi participated in new student orientations during the summer, and members of Texas Tech (Gamma Iota) were on-site for the first round of recruitment on August 15, 2021.
Alpha Phi held establishment events from September 2-12, 2021, and the chapter celebrated its first bid day on September 13, 2021.
After opening for extension in Fall of 2019, Alpha Phi submitted their written presentation to Angelo State in January 2020 to establish on campus. The on-campus presentation was scheduled for March 17, 2020, but was postponed due to COVID-19. During the delay, the Fraternity and Sorority Adviser kept in regular communication with Alpha Phi staff. In March 2021, more than a year after the first scheduled in-person presentation, Alpha Phi was invited to an on-campus presentation scheduled for April 26, 2021.
