The potential to grow into amazing grownups. The potential to create, lead, and thrive. The potential to do big things. Every child has potential. And every child could benefit from another mentor and friend to ignite it.

When you volunteer with Big Brothers Big Sisters of Southwest Michigan, you can be that spark. Sign up as a Big and you can help a child (Little) fully realize the potential they’ve had all along.

Everyday activities can mean everything

Mentor a child on your own or with your partner, as a Big Couple. You and your Little can share everyday activities you already enjoy. Play a game or sport. Go on a hike. Read or draw. Visit a park or museum. Or just listen and nurture their inspiration. The opportunities to make a big impact are limited only by your imagination.

Bigs and Littles meet in person for two hours twice a month for a minimum of one year.

Making a meaningful match

Finding a match that’s successful for both mentors and mentees is important. That’s why we make sure Bigs share common interests with Littles, so the foundation for their friendship is already in place. We call this “intentional matching,” and it’s a big part of what makes our approach special.

Each Big and Little is assigned a Mentoring Relationship Specialist, who checks in, provides consistent coaching and support for the entire friendship.

Ready to get started? The first step to a match is completing our online application. You can also learn more about our enrollment process on our blog.

High School Bigs

This unique program takes place at elementary schools, matching high school student mentors (Bigs) with elementary school student mentees (Littles). Littles benefit from having a Big, and High School Bigs benefit by developing their social, leadership, and future career skills.
