Thornton Tomasetti Leadership
As an independent firm, our leaders are employee-shareholders of the firm, with no shareholder holding more than 6% of outstanding shares. We follow a matrix structure, in which our technical staff belong to both a practice and a region. Project teams are assembled to match client requirements, and may draw from across both regions and practices.
