Mark McCully
When Mark McCully was growing up on a diversified Illinois farm, he didn’t imagine a future that included CEO of the American Angus Association on his resume. Yet, his background — full of experiences from the show ring to the sale barn to the meatcase — prepared him to lead the nation’s largest beef breed registry. It’s a post he’s held since 2019.
Mark previously served in various roles at Certified Angus Beef and managed the Beef Improvement Program for Southern States Cooperative. He is a graduate of Western Illinois University and did graduate work and coached livestock judging at Michigan State University.
He spends his days both in the big picture and dialed into the details trying to do what’s best for all Association members.
Mark and his wife, Gerry, have two grown children, and live in Saint Joseph, Mo.
