By Scout Nelson

South Dakota State University has hired Mandy Marney as the new Director of SDSU Extension and associate dean of the College of Agriculture, Food and Environmental Sciences. She began her new role on June 22, 2026.

“Dr. Amanda Marney brings a wealth of experience and leadership in extension to SDSU,” said Joe Cassady, SD Corn Endowed Dean. “I couldn't be more excited to have her join the College of Agriculture, Food and Environmental Sciences administrative team.”

Before joining South Dakota State University, Marney served in similar leadership roles at the University of Wyoming. She has also worked with Kansas State University Research and Extension, the University of Missouri Extension, and the Missouri Agricultural Experiment Station. She earned a bachelor’s degree in agricultural journalism, a master’s degree in environment and behavior, and a doctorate in human environmental sciences from the University of Missouri-Columbia.

SDSU Extension serves as the outreach arm of the university and includes a network of hundreds of employees across South Dakota. The organization provides research-based information to help improve the lives of people throughout the state. Its work focuses on four main areas: Agriculture and Natural Resources, Community Vitality, Family, Food and Wellness, and 4-H Youth Development. Programs are offered through offices in nearly every county and eight regional centers.

“One of my biggest goals in my first year is to spend time listening, learning and building strong relationships across SDSU Extension and the communities we serve,” Marney said. “My goal is to help create an environment where people feel supported, connected and empowered to innovate while still honoring the strong foundation and traditions that have made SDSU Extension successful for generations.”

“Extension is a calling for me. It reflects who I am, how I serve, and the way I choose to engage with communities,” Marney said. “As I step into this role, I want South Dakotans to know that I am excited, energized and ready to listen, learn and work alongside them. My husband, Neil, and I are looking forward to making South Dakota our home and contributing to the bright future of this state.”
