As a Big Brother or Big Sister, you will:
- Be matched with a child or youth based on shared interests
- Spend time together regularly through shared activities
- Build encouragement, consistency and positive mentorship over time

Mentorship Makes a Lasting Difference
In this video, meet Big Joanna and Little Gabbie—a mentor‑mentee match that highlights how CASL creates safe, supportive spaces for youth to learn, grow, and build confidence. Through guided activities, cultural connection, and consistent relationships, CASL’s site‑based program helps young people thrive both inside and outside the classroom.
“Watching my mentee grow into a confident young man and go on to earn a full scholarship to Stanford made every session worth it. Being a mentor isn’t just about giving guidance — you form a real bond, and you get just as much out of it as your little does.”
