The Rho Omicron Chapter, the newest chapter in Province 27, was chartered on November 7, 2009.

The Rho Omicron Chapter is a group comprised of the men of the highest ideals within our Mason Community. The Chapter has initiated its Alpha Class in the Spring of 2010, has become a well-known source of music on campus, and has become a strong supporter and advocate of George Mason's School of Music. We like to Step Sing at different places on campus, participate in moonlight serenades, support music faculty with projects and concert attendance, and have discussions about our fraternity and its object.
