The Office of Student Affairs at Yale Law School helps law students navigate their legal education from Orientation to Graduation. We support students individually and collectively, manage law journals, student organizations, and moot court programs.  We promote student life, diversity and inclusion initiatives, wellness activities, community building initiatives, and serve as the primary resource for law students at Yale Law School.  We hope to be the the first place law students stop with questions or concerns.
