Mark Rasmussen, Northwest District

I am from NE Nebraska and have a long history in farming and agriculture.  After receiving a BS and MS in agriculture from the University of Nebraska-Lincoln I farmed for several years.  The farm grew in size focusing on production of forages and grain (700 acres) and beef cattle, both feedlot (700 head annually) and 100 cow /calf pairs.  But in the farm crisis of the 1980s the bank we used in Sioux City failed and things turned chaotic.  So I gave up active farming to return to graduate school at the University of Illinois, Urbana-Champaign where I studied ruminant physiology and microbiology doing research to enhance forage-based beef production.  After UIUC I worked for Eastman Kodak in Tennessee on projects related to ruminant nutrition and cellulose biochemistry.  I then moved to Ames, IA to do research work at the USDA National Animal Disease Center.  While at NADC I obtained an MBA from ISU learning much about technology transfer.  After USDA I did algae research related to carbon capture which was supported by Xcel Energy in the Twin Cities.  When Congress failed to act on climate legislation at that time, I moved to Washington DC area to work for the FDA’s Center for Veterinary Medicine and led a research group on antimicrobial resistance. 
 
I returned to Ames in 2012 to become Director of the Leopold Center for Sustainable Agriculture and retired from LCSA and ISU in 2021 as an emeritus professor having really never left agriculture across the years. Along with research publications, I hold 7 patents.  One of which was successfully commercialized and was recognized in 2012 by ISU as ranking 14th in lifetime earnings for technology transfer and commercialization.

Berleen Wobeter, Northeast District

I am a lifelong Tama County resident, raised on our family farm in the northern part of the county. Our farm resembled the majority of past small diversified farming operations with a strong emphasis on conservation practices.  Our family also operated a small evergreen nursery on the farm, growing many plants from seedlings.
 
I graduated from Iowa State University with a degree in education, after which I moved to my husband Pete’s family farm in the southern part of the county.  There we raised our two children while Pete operated the farm and I pursued career opportunities in education, never ignoring my passion for gardening, landscaping and appreciating rural life.
 
I have been witness to many years of change in our rural communities, landscapes and farms.  It is my passion and new focus of interest to understand what is prompting this change since our farm neighborhood was threatened by the encroachment of one of Iowa’s industrial agriculture giants. This was my wake-up call and it could not be ignored. My goal is to understand the causes of these many years of change and the effects on our farmers, farming operations, our state, our food, and our environment, followed by educating others with the hope we can move future change in a more healthy sustainable direction.  We must do this work together with other like-minded citizens if we are to make an impact.  I look forward to my work on the Iowa Farmers Union Board, an organization with a vast history of work I now appreciate and hope to contribute to..

Shaffer Ridgeway, Northeast District

Shaffer Ridgeway is a conservationist with the USDA who has dedicated his career to helping farmers care for their land and build healthy, sustainable operations. A native of Alabama, he grew up on a small cow/calf operation owned by his father and went on to earn a bachelor’s degree in Agribusiness from Alabama A&M University.

In 2000, Ridgeway moved to Iowa to work as a Soil Conservationist for the Natural Resources Conservation Service (NRCS), where he has served in several roles over the years, including his current role as District Conservationist in Black Hawk County. After many years advising farmers on conservation practices, he began applying those same principles outside of work.

In 2019, Shaffer and his wife, Madelyn, founded Southern Goods LLC, a produce farm focused on bringing Southern vegetables to Midwestern tables. The Ridgeways market their products through the Waterloo Urban Farmers Market and the We Arose Co-op, and their operation also includes feeding cattle that are directly marketed to local consumers.

Over the last several years, Ridgeway has become a strong advocate for regenerative agriculture and for teaching producers the importance of following the five soil health principles. Shaffer and Madelyn live in Waterloo, Iowa, with their three sons — Solomon, Max, and Jacoby.

Thomas Burkhead, Student Representative

Thomas Burkhead is a second-year law student at Drake University Law School with a deep connection to agriculture, food systems, and rural communities in Iowa. A fifth-generation Iowan, Thomas grew up between his family’s Century Farm in rural Calhoun County and the city of Des Moines. Those experiences continue to shape how he understands the relationship between land stewardship, food production, and public policy.

Thomas’s interest in agricultural and food law is grounded in practical experience and civic engagement. As an undergraduate at Drake, he worked at the Agricultural Law Center, where he helped organize farmers and contributed to the development of the Greater Des Moines Buy Fresh Buy Local campaign. After graduation, he worked across multiple parts of the food system, from sustainable farming and local food production to environmental and agricultural services, gaining firsthand insight into the challenges facing farmers and communities.

Thomas has been privileged to be involved with the Iowa Farmers Union for many years, and the organization has played a formative role in shaping his understanding of agriculture as a shared civic responsibility. As a student representative, he is grateful for the opportunity to learn from farmer-led dialogue, democratic policy development, and a tradition rooted in fairness, education, and mutual care. These experiences now directly inform his legal studies, which focus on sustainable agriculture, food systems, and water quality.

As a student and advocate, Thomas is particularly interested in how legal frameworks allocate responsibility for environmental impacts, food access, and rural wellbeing, and in how law can better support long term community resilience. He approaches food and agricultural law as work that is both practical and principled, grounded in lived experience and guided by an ethic of care for people, land, and water together.
