Callahan Hall, Oregon State University

Callahan Hall houses approximately 350 residents on 5 floors. There is a full-time resident director and ten resident assistants. Rooms are co-ed by neighbor with a men's and women's bathroom at the center of each floor.

Callahan Hall is home to the EXPLORE Living-Learning Community, in partnership with the University Exploratory Studies Program. This community is the 4th floor of the building. EXPLORE is a space focused on major and career exploration. Students in this community will be able to explore their interests, values and goals by gathering information through programming, experiential learning, community building and coursework. Students will also have the opportunity to connect with faculty, staff and other students in exciting ways as they explore options outside the classroom. 

First year students in any major who are committed to exploration are invited to join EXPLORE.

Starting Fall 2017, each hall will have a mix of gender-specific and non-gendered bathrooms.
