Former American Coalition for Ethanol (ACE) Communications Director Katie Muckenhirn (maiden name Fletcher) has taken on the new role of Vice President of Public Affairs at the organization’s office based out of Sioux Falls, South Dakota. Muckenhirn will continue to manage the organization’s media relations, while assuming a larger role in ACE’s public policy efforts and planning of ACE’s Washington, D.C. fly-in and annual conference.

ACE CEO Brian Jennings says employing Muckenhirn’s experience as the organization’s communications director for nearly five years, to take on these additional activities is a natural transition as the organization restructures and seeks new staff roles.

“We are ecstatic Katie is taking on this new and elevated role to showcase her work ethic and skill in continuing to oversee ACE’s communication strategy, while planning for our two main industry events each year,” Jennings said.

“I’m thrilled to grow in my role on the ACE team and continue building upon ACE’s superior reputation of hosting must-attend fly-ins and conferences,” Muckenhirn said. “As Vice President of Public Affairs, I hope to leverage the experience I’ve gained over the past five years to continue broadening ACE’s reach amongst its constituencies, bolster ACE’s political influence, and provide top-notch events for ACE membership and the industry.”

As Muckenhirn transitions into this new role, ACE is seeking a full-time Communications Manager to join their team. Interested applicants should contact Shannon Gustafson at the ACE office at

Muckenhirn joined the ACE staff in 2017 after nearly three years of writing and editing for BBI’s Ethanol Producer Magazine, Biomass Magazine and Pellet Mill Magazine and providing event support for the International Fuel Ethanol Workshop & Expo.
