Our Team


Black Hills Community Loan Fund was established as the Teton Coalition nearly 30 years ago. The organization originally focused on delivering financial literacy and homebuyer education services to the Native American community of Rapid City, South Dakota. Since then, we have grown and evolved into a Native community development financial institution (CDFI), certified by the U.S. Department of Treasury. Native CDFIs are nonprofit loan funds that help Native communities thrive and grow by increasing access to credit, capital, and financial services.
