Who We Are

D&T Contractors was built on hard work, shared vision, and a commitment to quality. Founded by James DeSalvo and Mark D. Tanner, the company began as a simple conversation between two men who worked long hours side by side — each bringing their own strengths, experiences, and ambition to the table.

What started in the labor department evolved into something far greater. Mark’s long-standing industry relationships and field experience paired perfectly with James’s sharp business sense and quick grasp of operational needs. Together, they laid the foundation for what would become one of the most trusted labor and electrical support companies in the Gulf Coast region
