About Us

Our Story

When Leonard R. Cowan took his many years of experience in the concrete industry and founded L.R. Cowan Concrete Co., Inc. in 1979, he was driven by a passion to provide quality concrete work.  When he started the company, it was just him and a few other employees. 

Leonard started the Company doing residential projects.  Most were large custom homes (which have numerous challenging uses of concrete) and small tract communities.  In the early 1980’s he started to concentrate on moving the Company towards commercial construction and began with small jobs from fast food facilities to banks.  The Company moved into their first office in 1985, around the same time as the economic boom began, and made another shift from small commercial projects to larger ones.  Instead of building tract homes, we began working on the essential components that comprise completion in the community; including schools, grocery stores, retail centers, churches, and home improvement stores.   

As the company continues to grow, we moved into our new office that we designed and built in north Phoenix in 1995.  With Arizona expanding, we will continue adding infrastructure around the valley.
