Partnership is integral part of the Drees & Sommer Group corporate structure and is reflected in the relationship between senior managers and employees regardless of experience, and the way we operate in the marketplace.

As Managing Partners, the Partners run the Drees & Sommer Group. Our Project Managers tackle the nuts and bolts of business, working in teams to realize projects. Employees who take responsibility for an entire project become Project Partners. And those who develop expertise in a specialized field become Senior Project Partners. If they assume additional responsibilities, they can become Associate Partners. This means that every employee has the opportunity to advance within the partnership – through personal ability, commitment and appropriate experience.
