Beta Beta Beta (TriBeta) is a national biological honor society for students who wish to further their understanding and appreciation of biological study. Consistent with Southwestern University’s core values, the Delta Alpha (ΔΑ) Chapter encourages students to engage beyond the classroom through direct service, intersectional learning, and group discussion. Since TriBeta's founding in 1922, more than 200,000 persons have been accepted into lifetime membership, and more than 626 chapters have been established throughout the United States and Puerto Rico.
