Who We Are

Established in 2004 and headquartered in Santee, South Carolina, SLS’s experienced HR professionals conduct objective workplace investigations regarding discrimination and harassment complaints. Our investigations are recommended by many legal firms as they are thorough and we provide a detailed investigation report to help senior management determine the necessary response after the investigation is concluded.

Our firm also provides 360 Performance Reviews and other Senior HR-Level assistance in employee management.

We also provide assistance in matching employer needs with other HR firms in their area.
