Big Brothers Big Sisters of the Black Hills, founded in 1961 and based in Rapid City, matches children with caring adult mentors in one-to-one relationships across the Black Hills region of western South Dakota. Audrey Nordine serves as executive director. The agency is at 425 Kansas City Street in Rapid City. Website bigmentors.com; phone 605-343-1488.
The agency matches a child (a Little) with a vetted volunteer adult mentor (a Big) in a one-to-one relationship supported by professional staff. The relationship gives a child a consistent, caring adult presence, which research links to higher confidence, stronger school engagement, and resilience.
Based in Rapid City, the agency provides mentoring to children across the Black Hills, the population center of western South Dakota, building matches that meet regularly for activities and conversation.
Founded in 1961, Big Brothers Big Sisters of the Black Hills has provided mentoring in the Rapid City area for more than six decades. That longevity has helped the agency build the donor and volunteer base that sustains its work in a relatively small western South Dakota market.
Audrey Nordine serves as executive director, leading the agency from its office at 425 Kansas City Street in Rapid City.
The agency serves Rapid City and the surrounding Black Hills, the western South Dakota region anchored by Rapid City, the state's second-largest city. The Black Hills draw on a mix of urban, small-town, and rural communities, along with nearby tribal areas.
As with most BBBS agencies, demand for mentors exceeds the supply of screened volunteers, so the agency continually recruits Bigs who can commit to a long-term, consistent relationship with a Little.
To become a Big, visit bigmentors.com or call 605-343-1488. Volunteers complete an application and screening process, then are matched with a Little and supported by agency staff throughout the relationship.
Mentoring in a smaller market depends heavily on local volunteers, so the agency welcomes adults across the Rapid City area who can give a child consistent time and attention.
Donations can be made at bigmentors.com. The agency is a 501(c)(3) organization, so gifts are tax-deductible. Corporate partnerships, foundation grants, and individual giving fund the mentoring work across the Black Hills.
Gifts that fund match support, the staff time behind each match, help keep relationships safe and effective over the long term.
South Dakota has youth-serving organizations including Boys and Girls Clubs and community programs. For one-to-one, professionally supported mentoring in the Black Hills, Big Brothers Big Sisters of the Black Hills is the dedicated agency, with more than six decades of history.
Its focus on sustained individual relationships complements the group programming other organizations provide across the region.
