List of Gamma Sigma chapters

Gamma Sigma was the first international secondary school fraternity. It was originally founded as a literary society in 1869 at the Brockport Normal School in Brockport, New York, and chartered at least 119 chapters at normal schools and high schools in the United States and Canada. The organization no longer has active chapters at the secondary school level, with the last active chapter ending around 1994. However, it has an active alumni based in the Niagara Region, Ontario, Canada.
