ABOUT US
SOLUTIONS WITH INTEGRITY
WE DELIVER THE HIGHEST LEVEL OF UNCOMPROMISED DEDICATION AND EXCELLENCE.
In 1995, the three Sullivan brothers founded SLS with the goal to uphold integrity in every job, project and action.
For more than two decades, they and our leadership team have helped the company stay true to its mission by providing the highest quality service, while delivering projects on-budget and on-time. Our proven track record of excellent production ratings in the face of enormous challenges has made us a leader in the industry.
We are headquartered in Galveston, Texas, with offices throughout the United States and Caribbean Basin. Our national presence and our hands-on team of project executives, managers, superintendents and construction professionals allow
us to quickly mobilize and service any assignment, no matter the size or location.
