Mark has been training 40 years to inspire students in the agribusiness management program. He carved out a 20-year career as a manure visionary and loves to tell folks he got his job because “he knew his ‘manure.’”

Emissions and new markets are often managed by making the most apparent choice, but the obvious solution is rarely the best option. Effective, sustainable solutions to management of societies' organic residues require a deep working knowledge of both the market and legal systems. Mark built his expertise by innovating with undervalued organic residues and biomass in food, feed, energy, and environmental markets--emerging agribusiness frontiers.

Mark has worked all over the country, in addition to operating his own hog farm and biomass energy consulting company. He helped establish private ownership rights for US fish farmers and helped contract poultry growers understand their performance contracts. He developed a rural power plant for the State of Indiana that would run off of locally available municipal and agricultural residues. He examined the value of energy crops at the University of California, Davis, verified analyses of US government data for USDA and EPA, and wrote a column for BioCycle magazine.

During his formative years, Mark spent two years in Nepal in the Peace Corps and six months working on a farm in Germany. Along the way, he earned a PhD in agricultural economics focusing on production systems, two MS degrees in manure management, and a BS in agronomy. He came to Greenville University from the University of Missouri, where he reconnected with the joy of teaching while serving as Extension faculty. One of the aspects that drew him to the Grenville's Briner School of Business was the chance to inspire what Bob Briner calls “lambs that roar.”

“We can do this,” Mark says. “We can deliver sharp, confident agribusiness management graduates who will outperform graduates from larger programs.”
