Christopher Hyams

As a fourth-generation business owner, Chris Hyams knows what it takes to help ensure that his company’s clients, employees and sub-contractors stay happy. How? By making sure to treat everyone he encounters on the job with the same level of respect.

Chris started working at G. S. & S. Construction at the age of 15, pulling nails and pushing brooms. Working for the company through spring and summer breaks led him to being exposed to every aspect of the business. While working his way up the ranks, Chris studied construction management at Southwest Missouri State University (now Missouri State University). He completed his last nine hours of college credits while working full time as a carpenter at G. S. & S., and was a member of the Carpenters’ Union for nearly ten years.

In 1999, Chris moved out of the field and into the office, taking over the operations of the company. Today, he serves as the face of G. S. & S. Construction focusing on business development and engaging with new clients.

Chris is married with two kids. His hobbies include duck hunting and clay target shooting. He serves as president of the Board of Directors for the Great Rivers Habitat Alliance, which helps to preserve Missouri’s Big River Floodplains and Wetlands. Additionally, Chris is a past Board of Governors member of the Missouri Athletic Club and current Chairman of the club’s Rod & Gun Club. He is also active with the Boy Scouts of America.

Greg Bauer started working at G. S. & S. Construction in 1990 when he was just 20, driving a truck delivering materials. Over the years he took on more responsibilities, eventually focusing on the safety aspect of the construction industry.
