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.
