Field Personnel

SLG prides itself on finding top talent to fill managerial positions, but also on putting together the most effective crews for a given project. Currently we have approximately 35 full-time laborers, carpenters and superintendents on staff. No list showing key personnel would be complete without recognizing them. They are ultimately responsible for our successes, past, present and future.


No GC can be successful without the skill, dedication, and solidarity brought to every job by its subcontractors. We are inexorably intertwined and ultimately responsible for each other’s success. SLG is able to put together the most effective teams for its projects because we understand this is fundamental. Therefore, the best tradesmen in the business want to work with us – and we with them – to the benefit of the entire project team.
