Theta Pi Sigma (ΘΠΣ), formerly known as Delta Lambda Psi (ΔΛΨ), was started by Marc Garcia
in 2005 at UC Santa Cruz. There was a lawsuit with Delta Lambda Phi over the use of the initials DLP that resulted in a rename to Theta Pi Sigma. In 2015, the Alpha chapter of Theta Pi Sigma voted to stop using the misleading term frarority due to the gender binary connotations of the term. Theta Pi Sigma is the world's first regional queer-focused, gender-neutral Greek organization on the verge of becoming national with international aspirations.
