Our Story & Mission
Who We Are
Student Self Defense Advocates (SSDA) is a student-led project of Next Generation Advocates dedicated to empowering students through self-defense education and advocacy. Founded in response to rising violence—especially among students—SSDA educates on self-defense, creates awareness through social media, and promotes safer school environments.
Our mission is simple: help students feel safe, confident, and prepared—because every student deserves the power to protect themselves.
