Christina Oey

Executive Director

Christina has a master’s degree in Advocacy and Political Leadership with a Nonprofit Organization focus from the University of Minnesota, Duluth and a bachelor’s degree in political science from the University of Minnesota, Twin Cities. Christina serves on the Boards of Directors for the South Dakota Nonprofit Network and the Camp Unistar Foundation.

Amber McChesney

Business Manager

Amber, a lifelong South Dakotan, joined SDHC in December 2025. She brings over a decade of experience in operations and team development, with a strong foundation of streamlining processes and supporting organizational growth. With a background spanning strategic execution and people-first leadership, she is passionate about improving how people work—and how they feel in their roles. Outside of work, she enjoys spending time with her children, whose energy keeps life meaningful (and full of snack negotiations). When she sneaks some free time to herself, she can be found writing free-verse poetry, attempting to bake, or scouring thrift stores in search of the world’s most perfect coffee mug.
