Our People

Experience You Trust and a Team You Can Count On

For nearly 90 years, CORE has been building relationships — one project at a time. Our team combines deep industry expertise with relentless innovation, fostering a culture of continuous improvement that drives exceptional results.

Founded on Trust

CORE’s founder, Otto Baum, immigrated to Morton, IL, seeking a better life for his family. Known for his honesty and hard work, Otto applied for a loan in 1937 to start a masonry company, offering only his character and reputation as collateral. The loan officer’s simple words, “I trust him,” marked the start of our company, which now thrives across the U.S. with over 1,200 employees, rooted in the same trust and values Otto established. We live and breathe our CORE values – Integrity, Fairness, Continuous Improvement and Results – every single day. Let us show you how we’ll create the best builder relationship you’ll ever have.

Fort Worth Police Department
There were many obstacles that CORE and the entire team overcame. As the project scope changed by way of GCCS desires, the CORE team’s work was fantastic as they sought to conceptualize, design, price, and implement.

There were daily conversations had by both CORE and I that I appreciated having as a “touch base.” I was never surprised with the project’s many facets of completion.
