Company History

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. One of those first employees is still working with him to this day, showing the level of commitment and loyalty employees of L.R. Cowan have to Leonard and this company. Our Company boasts an average employee tenure of 8-9 years.

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 comprised completion in the community, including schools, grocery stores, retail centers, churches, and home improvement stores.

The Company continued to grow, and in the 90’s some of our notable projects included adding the roller coasters and log flume ride at Castle-N-Coasters, several Wal-Mart’s, Home Depots and Lowe’s, the Navajo Army Depot Training Facility in Bellemont, Az, ASU’s Karsten Clubhouse, several phases at Intel, Pinnacle High School in Paradise Valley, The Army National Guard Vehicle Maintenance, Fuel Storage Facilities and Hush House, Crossroads Church of the Nazarene, Mesa Spectrum (a 114,000 sf retail center), Maricopa County Health Services Building and the Terravita Clubhouse. With the housing market expanding, we added numerous elementary schools, middle schools and high schools. During this time we also moved into the new office that we designed and built in the North valley of Phoenix in 1995.

In the 2000’s we continued adding schools throughout the valley, with Comprehensive High School in Laveen, AZ being one of the largest at the time, and Sierra Linda High School in Tolleson, AZ. We also went to Kingman, AZ and did the Elementary and Middle Schools. We did several phases of work for the City of Peoria including their Facilities Administration Building, Municipal Operations Center, and Transportation Facility. Other notable jobs included the First Assembly of God Youth Center, St. Thomas Aquinas Church, Skycast Manufacturing Plant in Eloy, AZ, the Scottsdale Quarter Retail Center, South Mountain Community College Library, and we returned to the Army National Guard to add the Field Maintenance Facility. We also worked on several phases of the SkyTrain Expansion at Phoenix Sky Harbor Airport, a couple of new centers for the Salvation Army, and the GSA/FBI Building Site work, as well as several Fire Stations and City Parks. Additionally, we worked on several of the “Field of Dreams” ball fields that were sponsored by the Diamondbacks all across the valley.

More recently, we have worked on the Gateway Community College and Central Arizona Community College. We went to Sahuarita, AZ to complete the High School and Middle School, and to Coolidge for the High School and several other expansions and additions. We are proud to have been a part of the Centennial Plaza for the City of Peoria, which pays homage to Arizona’s history, and the Peoria Community Center and Park on 83rd Avenue, as well as Xavier Prep School’s Founders’ Hall, the ASU New Business Facility, Larry H. Miller Toyota and Dodge Dealerships in Peoria and the Phoenix/Mesa Gateway Airport. Among our larger projects are the Tanger Outlet Mall (372,000 sf) in Glendale, AZ and the decorative hardscape and concrete paving (272,000 sf) at the Gilbert LDS Temple and Meetinghouse.
