Welcome to the Oregon State Chapter

Alpha Sigma Chapter House

The Alpha Sigma chapter of Alpha Tau Omega was founded at Oregon State University in 1882. We are the oldest fraternity on campus, and we are the first Alpha Tau Omega chapter in the Northwest. We currently have about 25 members, who are involved in many on-campus clubs, honor societies, and intramural sports teams.

As the National Leadership Development Fraternity, we are looking for driven college men who we can help become the leaders of tomorrow. Whether in academics, philanthropy, or social events, we strive to excel and lead others by our positive examples. If you are interested in learning more about ATO, look at our recruitment page, email our recruitment officer by clicking here, or stop by our house for a visit. Our house is located on the corner of 26th and Van Buren. Here's a map.

This term we did our philanthropy which was a Dodge Ball Tournament. We teamed up with Kappa Alpha Theta and the OSU Dodge Ball Club.
