Join Lillian Samuel, CEO of Big Brothers Big Sisters of the Bay Area, at Commonwealth Club World Affairs for an inspiring talk: “When Kids Have Mentors, Cities Get Stronger.” Backed by powerful national economic data, Lillian will discuss how mentoring doesn’t just change one life—it uplifts entire communities. Youth with mentors are more likely to graduate high school, attend college, and earn significantly more as adults. Mentorship narrows income gaps and boosts local economies.
Through inspirational local case studies, she’ll share how even a single match between a Big and Little can ripple out to benefit families and neighborhoods. This is more than a program—it’s a proven strategy for creating stronger, more connected cities. Don’t miss this opportunity to learn how one relationship can transform a life and a community.
