Ken Mulzer Honored with IMAA’s 2022 Keystone Award

The Indiana Mineral Aggregates Association (IMAA) presented its 2022 Keystone Award to Ken Mulzer, president of Mulzer Family of Companies, at the association’s annual Winter Workshops & Award Banquet held in Indianapolis.  

The award, first given in the late 1990s, 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, 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, Mulzer has exhibited the traits of a tireless industry advocate in many ways, especially within the inner workings of IMAA.  

Most notably, Mulzer 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. 

Mulzer 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.
