Welcome to Sigma Chi

The Alpha Theta chapter of Sigma Chi at MIT is a proud and accomplished organization with a rich history dating back to 1882. As the oldest continuous fraternity at MIT, we have a strong tradition of excellence and a deep connection to the Institute. Our members come from diverse backgrounds and academic fields, united by a strong bond of brotherhood. Our chapter is committed to academic distinction and character development. We seek to live out our three great aims, the values of Friendship, Justice, and Learning.

In addition to our focus on personal and chapter development, we value social connection. Our chapter’s social calendar is renowned for its array of events including formals, brotherhood retreats, mixers, and lively parties. The connections made here endure a lifetime and link our brothers to generations of alumni.

Our house, a beautiful and historic brownstone located in the heart of Boston’s Back Bay neighborhood, recently underwent a $6 million renovation. It contains amenities including a full-service elevator, air conditioning, a maker space, an abundant library, and a large bar. We are a short walk to campus, and our distance from MIT allows us to foster a close-knit community of hard-working and ambitious individuals while giving us the chance to explore Boston proper.

We are committed to providing a well-rounded college experience for our members. We look forward to welcoming new members to our brotherhood and invite you to learn more about us by visiting our website, attending one of our events, or reaching out to a member of our chapter.
