John Lee, P.E. | Director of Business Development

John Lee is the Director of Business Development at the Cemstone Companies, holding over 15 years of experience with our organization. In his prior role at Cemstone, he successfully oversaw the civil and engineering sales group.

With over 30 years of experience, John has actively contributed to the development of numerous large commercial and municipal projects in the Twin Cities construction market. He spent 17 years at Twin City Testing/Element, where he led the development and implementation of International Code Council Evaluation Service testing programs for various building materials, including concrete anchorage.

John earned his B.S. in Civil Engineering from the University of Minnesota. He is a registered professional engineer in Minnesota, Iowa, Wisconsin, Illinois, Florida, and North Carolina.

Lee says, “I am continually fascinated by the challenges we encounter in pushing the boundaries of concrete and how both the material and we, as individuals, respond to them. For me, seeing how the expectations of slab on grade performance has increased in the last 8 years is remarkable. Being a resource to homeowners, designers, and contactors on the use of fibers and joint reduction, like Cemstone’s Latitude system, has been one of the most rewarding things I’ve done in my 32-year career.”

Grothaus says, “During my time at Cemstone, I have enjoyed educating the public transportation sector about the resources and solutions that our Cemstone team of companies can supply. We are consistently known for our blue trucks delivering quality ready-mixed concrete, but what I am really enjoying is learning more about all of the products and services that we create, produce or supply.”
