What Is a Big Sib?

A Big Sib is an upperclass Stanford student who serves as a peer mentor to frosh students to help ensure a successful first year.  Big Sibs share their knowledge of resources on campus that helped in their own frosh transition as well as their knowledge of the community and how to become involved.

Applications to be a Big Sib are available until Sunday, September 10, 2023. Apply with other co-Bigs or as an individual looking to create a family! If you and your SibFam choose to apply, please note the program changes and keep in mind the time commitment and dedication we ask of you.
