The Sigma Phi Society, founded on March 4th, 1827, at Union College, is the second oldest Greek fraternal organization in the United States and the first to establish a chapter at another college, making it the oldest national Greek organization in the country.

The founders envisioned a small community of men, and that vision has stayed with Sigma Phi to the present day. Expansion to other chapters has been limited and has only occurred at the highest quality institutions.  The intimacy of Sigma Phi allows for a community where the development of individuals remain the focus, and where friendships formed in college last your entire life.​

One of the four founders of Sigma Phi, Thomas Bowie, went on to become a representative in the United States Congress. This started the tradition of contribution to the community that brothers continue to foster. Such contributions are as diverse as the brothers themselves, with many excelling in private industry, education, and public service.

The Alpha of Vermont chapter at the University of Vermont (UVM) was founded on March 4th, 1845, as one of the earliest Greek organizations on campus. Despite initially lacking a dedicated house, early members were highly committed to the Society's ideals.

The first classes of the Alpha of Vermont included some of the brightest minds at UVM and in the state, with members going on to become: Newspaper Editors, Civil War officers, Trustees & Professors, judges, mayors & businessmen.

As the chapter grew, the Alpha of Vermont procured land and completed its home at 420 College Street in the later part of the 19th century.

Throughout the 20th century, the chapter continued to serve the University and the country, with alumni contributing as administrators, professors, trustees, & serving in the armed forces (WWI, WWII, and beyond). Today, the Alpha of Vermont boasts an alumni base over 500 strong and continues to see its members thrive globally in politics, business, academia, and art, continuing a nearly 180 year tradition of excellence.
