Phi Sigma Rho (ΦΣΡ; also known as Phi Rho or PSR) is a social sorority for individuals who identify as female or non-binary in science, technology, engineering, and mathematics.[2][3] The sorority was founded in 1984 at Purdue University.[4] It has since expanded to more than 40 colleges across the United States.[4]


Phi Sigma Rho was founded on September 24, 1984, at Purdue University by Rashmi Khanna and Abby McDonald.[5] Khanna and McDonald were unable to participate in traditional sorority rush due to the demands of the sororities and their engineering program, so they decided to start a new sorority that would take their academic program's demands into consideration.[5]

The Alpha chapter at Purdue University was founded with ten charter members: Gail Bonney, Anita Chatterjea, Ann Cullinan, Pam Kabbes, Rashmi Khanna, Abby McDonald, Christine Mooney, Tina Kershner, Michelle Self, and Kathy Vargo.[2]

Phi Sigma Rho accepts students pursuing degrees in science, technology, engineering, and mathematics who identify as female or who identify as non-binary. The sorority made the decision to include non-binary students in all chapters in the summer of 2021.[2]

Phi Sigma Rho has grown more than 40 chapters nationally.[5] Its headquarters is located in Northville, Michigan. Its online magazine is The Key.[6]


The colors of Phi Sigma Rho are wine red and silver.[5] The sorority's flower is the orchid, and its jewel is the pearl.[5] Its mascot is Sigmand the penguin.[5] Its motto is "together we build the future."[5]


The objectives of Phi Sigma Rho are:[7]


Phi Sigma Rho's national philanthropy is the Leukemia & Lymphoma Society.[8]

The Phi Sigma Rho Foundation was established as a separate nonprofit organization in 2005.[8] It supports the educational and philanthropic efforts of the sorority's members and offers merit-based scholarships to sorority members.[8][9]
