Indiana Mineral Aggregates Association (IMAA) presented the 2022 Keystone Award to Ken Mulzer, President of Mulzer Family of Companies, at the association’s annual Winter Workshops & Award Banquet held in Indianapolis last week. The award, first given in the late 90’s, recognizes an individual in the aggregates industry who has shown exceptional leadership and outstanding dedication to advance the goals, growth, and well being of the Indiana aggregates industry. During the presentation, an IMAA Representative explained further, “By definition, the keystone is the topmost stone of an arch, popularly thought of as especially holding the others in place.”

Growing up in the third generation of a family whose legacy in the aggregate industry is still growing strong throughout Southern Indiana and beyond, Ken Mulzer has been a dedicated supporter of Indiana aggregates his entire career. From his first role at Mulzer Crushed Stone cleaning the shop at age 15, Ken has exhibited the traits of a tireless industry advocate in many ways, especially within the inner workings of IMAA. Most notably, Ken was a major supporter of the creation of WLMA (Women Leaders in Mining & Aggregates), he served on the Board of Directors and the Executive Leadership Panel, and represented membership as President in 2021. Ken also participated on the Build Indiana Council as an appointed IMAA Representative for three years. He is a 2022 Inductee of the Indiana Ready Mix Concrete Association Hall of Fame, joining a distinctive class of accomplished Ready Mix leaders, including his father, Ken Mulzer Sr., who was also the first recipient of the IMAA Keystone Award in 1998. Congratulations Ken!
