Indiana association names new director

By |  June 14, 2018


The Indiana Mineral Aggregates Association (IMAA) board of directors named Calvin Lee as its executive director.

Lee succeeds Robert Jones, who is retiring after 16 years as the association’s executive director. The change in leadership will be effective on July 9.

Lee’s career includes 20 years with the Indiana Department of Transportation, where he rose to the position of assistant deputy commissioner. Lee spent the past 11 years with Indiana Constructors Inc., most recently as the director of professional development.

“Calvin looks forward to continuing to make IMAA work effectively for all its members and understands that IMAA cannot be strong without the participation of its members and associate members,” says Gene Yarkie, a regional vice president at Rieth–Riley Construction Co. and IMAA president.

IMAA, which represents more than 90 percent of aggregate production in Indiana, aims to solve common problems of the Indiana aggregate producing industry, principally in the areas of aggregate specifications, mine safety and reclamation, air and water pollution, legislation, research for improvements in aggregate used, increased public awareness of the importance of aggregate products in their daily lives, and broadening the use and application of aggregate in Indiana.
