Empowering potential in our community’s youth is as simple as spending time with a child or teen for a few hours, a couple times a month. No expertise needed! You aren’t a therapist or a substitute parent. By simply being there, you help change a child’s perspective, giving them a sense of future and the opportunity to live up to their full potential.

For over 100 years, the Big Brothers Big Sisters mentoring model has empowered youth to live up to their full potential. Studies continue to show that mentoring can help kids stay out of trouble, do better in school, and get set up on a path to success into adulthood.

There are many ways to defend potential in our community’s youth:
- Become a Big
- Donate
- Participate in fundraising events
- Planned giving
- Donate goods & clothing through Hartsprings
- And so many more!
our impact
In 2025, Big Brothers Big Sisters of America shared the findings of a study that proves that – over time – mentored youth have greater enrollment in higher education, increased salaries, reduced dependency on social services, and improved behavioral outcomes.
This groundbreaking study demonstrates the transformative power of mentorship in shaping young people’s educational, economic, and social trajectories, and explains how mentorship programs like Big Brothers Big Sisters can serve as scalable solutions to reduce socioeconomic disparities.
