June 10, 1921, marked the momentous occasion of taking the second chapter into the Sigma Alpha Rho Fraternity. In preparation for this expansion, the fraternal and ritual minded members of the group polished, revamped, and rewrote the rituals and rites of Sigma Alpha Rho, until finally they assumed the proportions and composition that exist today. Thus, the Sigma Chapter was introduced, and with a designation as a Sigma Chapter came the appellation of the Phi Chapter to the original body, and SAR became an institution rather than a group.
