She is a graduate of the Greater Kansas City Chamber Centurions Leadership Program (Class of 2014) as well as the Greater Des Moines Leadership Institute (Class of 2022). She is also active in the Women’s Transportation Seminar (WTS), an organization focused on attracting, sustaining, connecting, and advancing women’s careers to strengthen the transportation industry. She currently serves on the Iowa Chapter Executive Board of Directors as Secretary.
Co-presenting with Stephanie as a 2023 Visiting Science Scholar is her husband, Joshua Hemberger. Joshua attended Grant Wood Elementary School and similarly attended Bettendorf Middle and High School, graduating in 2002. He also attended Iowa State University, where he studied Architecture. Joshua graduated with his Bachelor of Architecture in 2008 and minored in digital media.
Upon moving to Kansas City, Joshua began his career working at the Todd Bolender Center for Dance and Creativity, home to the Kansas City Ballet. Since then, he has been part of and has led a wide variety of work from housing to campus master plans. Joshua is now with Substance Architecture in Des Moines where he is currently leading the firm’s work on several projects with Indigenous non-profits and tribes of South Dakota.
Joshua strives to create architecture that inspires and improves both the human and environmental health of a community. He creates high-performance solutions with the aid of many tools to improve daylighting, thermal performance, and other aspects of buildings.
