Sigma Delta Omega is a sisterhood of scientists who highly value academic excellence, service, and membership growth. We are an interest-based sorority who all share a passion for science. Our organization contains a diverse group of people who are brought together by a common love for science.

Fall recruitment is the first and biggest event of the year and we would love to see as many potential new members as possible. The recruitment process is a holistic review of each person's values and character. Each recruitment event is a fun-filled evening of getting to know some of our sisters while we get to know more about each potential new member. SDO has been growing exponentially over the last couple of years and wants to continue growing!

Q: What council is SDO a part of?

A: SDO is a part of the Collective Greek Council which also includes 3 other interest-based Greek affiliations. The CGC is a large part of the Greek community at Oregon State and we continuously work with other councils as well.

Q: What are the housing options?

A: SDO is an unhoused sorority which is one of the ways that makes us such an accessible organization. Although we do not have a house, many sisters choose to find housing together and become roommates.
