As Executive Director for the Standing Rock Sioux Tribe under Chairwoman Janet Alkire, Kerry oversaw 64 programs and 103 employees, stewarding diverse funding streams and ensuring compliance with federal, state, and Tribal regulatory frameworks. Her tenure strengthened organizational accountability, modernized administrative systems, and elevated program performance across health, education, infrastructure, and community development portfolios. She is recognized for her ability to synthesize complex regulatory requirements into clear, actionable strategies that empower leadership and protect organizational integrity.

In her role as External Affairs Director, Kerry coordinated the Standing Rock Sioux Tribe's response after a Rapid City hotel publicly banned Native Americans from its property. Working across the Great Plains Tribal Chairmen's Association, she helped organize a unified intergovernmental response and called on the U.S. Department of Justice to intervene, citing violations of the 14th Amendment and the Civil Rights Act of 1964.  The efforts culminated in tribal leaders collectively delivering a "Notice of Trespass (Cease and Desist)" to the hotel, citing the Fort Laramie Treaty of 1868.  The unified tribal action drew national attention to the intersection of civil rights, sovereignty, and treaty law.

As External Affairs Director for the Standing Rock Sioux Tribe under Chairwoman Janet Alkire, Kerry collaborated on and helped implement several Tribal co-stewardship agreements with the USDA, advancing Standing Rock's role as a sovereign partner in federal public lands stewardship. One agreement included transitioning the Shambo allotment from cattle to bison operations, restoring cultivated lands to native grasslands, planting native woody species, and integrating a youth engagement component, returning the land to cultural and ecological integrity. 

As External Affairs Director for the Standing Rock Sioux Tribe under Chairwoman Janet Alkire, Kerry served as a primary liaison to federal agencies, congressional offices, North and South Dakota state officials, and national partners. She led high-level policy analysis, coordinated government-to-government consultations and public safety meetings, and advanced Tribal priorities through strategic communication and relationship-building. Her work has shaped national conversations on Tribal governance, public health, scientific research access, and Tribal co-stewardship of federally managed forests and grasslands.

Kerry secured grant funding to establish the first-ever Institute of Natural History, developed scientific research protocols, and built partnerships that brought STEM programming and paleontological research opportunities to Tribal youth and communities, an example of her ability to translate vision into funded, operational programs that advance economic opportunities in Tribal communities.
