Who We Are

Big Brothers Big Sisters of Greater Tri-Cities has been transforming the lives of children in the Tri-Cities area since 1985. We are a member agency of the oldest and largest youth mentoring organization in the United States, consisting of more than 350 agencies nationwide. Our agency currently serves the following counties: Sullivan, Carter, Hawkins, Washington, Kingsport, Johnson City and Washington, VA.

Our vision is that all children achieve their full potential.

Our mission is to create and professionally support one-to-one mentoring relationships that ignite the power and promise of East Tennessee youth.

Our Mentoring Structure is built around a long-term, trusting friendship with a caring adult who models and teaches skills, behaviors and perspectives. Changes in the child’s behavior, attitude and school performance emanate from the bond built between mentor and child. High-quality mentoring relationships of one year or more have the potential to produce enduring developmental outcomes for disadvantaged youth through two core Big Brothers Big Sisters programs.

Our Programs

Community-Based Mentoring
In the Community-Based Mentoring program, mentors and children share general community activities at least 2 times monthly, 2 hours per outing. They engage in recreational, educational and service activities in a variety of settings on a flexible basis for a year or more.

Site-Based Mentoring
The Site-Based Mentoring program takes place primarily in elementary schools and afterschool care facilities. Throughout the school year, children and mentors spend at least one hour each week sharing lunch, reading, doing homework, playing games or simply sharing what’s going on in the child’s life.

How To Get Involved


We believe that all children should have the opportunity to succeed in life and live up to their full potential. Some kids need someone to help them along that path. Spend a few hours 2-4 times a month, for at least a required year, as a mentor to a child and you can make a BIG impact in that child’s life. It’s rewarding and fun!

Enroll A Child

Could your little one use a Big Brother or Big Sister? For more than 30 years, we’ve been able to recruit, screen, match and support mentoring relationships that have changed the lives of thousands of young people – one child at a time. It all starts with the right role models. And Big Brothers Big Sisters is the place to start a relationship with one.
