Full Service Commercial Concrete Subcontractor


Lee Lopez

Owner / President

Lee Lopez

Lee started his career in the concrete industry in 1977 working for successful residential contractors in the Arizona market. His experience included form work, concrete placement and finishing, estimating, project management, and operations management.

In 1989, Lee cofounded Hardrock Concrete Placement Co., Inc. with his brother Larry. They started with small commercial projects and their offices were based out of their childhood house in Peoria. As revenue started to grow, so did their need for office space. In 2000, Hardrock built and moved into their current office, a concrete tilt-up building, in Phoenix.

Lee has always been a “hands on” owner and stays involved in all aspects of his organization, including Accounting, Estimating, Project Management, Purchasing, Business Development, and Field Operations. Because of Lee’s past experience in field operations, it is not uncommon for him to visit a job site and “put on his tool belt” to lead by example and educate his crews.

Lee’s vision, experience, hard work, determination, dedication, and leadership have been the most significant factors in Hardrock’s success over the past 26 years in business.

In 2002, Cindy moved to Tucson for a year to manage the Tucson office and update their procedures. During this time, she started working on a large project job site and began learning Estimating which was a natural transition with her appraisal background.

Cindy worked as an Estimator from 2004 through 2007. In March, 2006, Cindy was appointed Vice President as she continued her duties as an Estimator. During her employment she never was far from Lee’s mentoring and education on the “big picture” of the organization. In July, 2007 Cindy was appointed General Manager.
