Mission & Vision - Big Brothers Big Sisters of Big Sky Country BBBS Volunteer Application



Create and support one-to-one mentoring relationships that ignite the power and promise of youth.

About Us

Since 1973, this *Big Brothers Big Sisters has served thousands of local children in Southwestern Montana. Our mission is to create and support one-to-one mentoring relationships that ignite the power and promise of youth.

*(Previously operated as 2 affiliates)

* Big Brothers Big Sisters of Gallatin County

* Big Brothers Big Sisters of Park & Sweet Grass Counties

For more than 100 years, Big Brothers Big Sisters has operated under the belief that inherent in every child is the ability to succeed and thrive in life.

As the nation’s largest donor and volunteer supported mentoring network, Big Brothers Big Sisters makes meaningful, monitored matches between adult volunteers (“Bigs”) and children (“Littles”), ages 5 through 18, in communities across the country. We develop positive relationships that have a direct and lasting effect on the lives of young people.

Our local agency was founded in 1973 by a dedicated group of Gallatin County residents. In our first year, we served a handful of children. In our last fiscal year, our agency served 100’s of children within our service area. We are incredibly proud of this phenomenal growth, but we still have much more work to do.

In order to keep pace with the rapid growth of our community and the increase in the needs of children and families, we must meet this ambitious goal to reach more families. This requires engaging record numbers of volunteer Bigs and raising funds to support these matches.


All youth achieve their full potential.
