THOMPSON, DREESEN & DORNER (TD2)

Robert Dreessen joined Thompson, Dreessen & Dorner (TD2) in 1968 and became its President in 1974. In June 2010, he stepped down from that role and currently serves as Chairman of the Board. Though retired from day-to-day operations, Bob remains an active and influential figure at TD2. He makes frequent appearances at the office and continues to be an invaluable resource and a wealth of knowledge for the engineers and staff.

A pioneer in expanding the firm’s technical capabilities, Bob was instrumental in founding TD2’s in-house Soils Lab, a rare and innovative asset for civil engineering firms at the time. His expertise in geotechnical and site-specific challenges laid the groundwork for many transformative infrastructure projects throughout the region.

Throughout his career, Bob played a central role in shaping the built environment of communities such as Papillion and La Vista, Nebraska. His leadership guided the development of residential neighborhoods like Monarch Place, as well as public recreational facilities including Tara Hills Golf Course and Papio Bay Aquatic Center.

Bob Dreessen’s legacy is deeply embedded in TD2’s identity—through its people, its projects, and its enduring commitment to engineering excellence.

Doug Dreessen, P.E., is President of Thompson, Dreessen & Dorner (TD2), representing the second generation of leadership at the firm. He assumed the role in 2010, succeeding his father, Bob Dreessen, and has since led the company with a focus on strategic growth, technical excellence, and client service.

Doug’s journey with TD2 began in 1975 when he was just 14 years old. He started in the field, gaining hands-on experience in land surveying, geotechnical engineering, materials testing, and construction observation. This early immersion gave him a practical foundation that would shape his approach to engineering and project management. Over the years, he has overseen the design and construction of numerous residential and commercial subdivisions across the Omaha metro area and throughout eastern Nebraska.

Before becoming President, Doug led TD2’s Civil Engineering department for more than a decade. His professional experience spans drafting and designing grading, sanitary and storm sewer systems, paving, and water infrastructure. He is also skilled in cost estimating, contract administration, proposal development, and public presentations. Known for his collaborative leadership style, Doug works closely with governmental agencies, contractors, engineers, environmentalists, utility companies, and public stakeholders to deliver complex, multi-phase projects.

Doug has been instrumental in expanding commercial development in Omaha and surrounding areas. Signature projects under his leadership include Hillsborough near 144th and Maple—an integrated development blending residential, recreational, and commercial elements—as well as Huntington Park and American Interstate Plaza near 156th and Maple. In Sarpy County, he carried forward his father’s legacy with developments like Shadow Lake Towne Center and Midlands Place in Papillion, further advancing the region’s commercial and economic footprint.

As President, Doug guides TD2’s management team and champions the firm’s expansion across Nebraska. His ongoing mission is to promote TD2’s capabilities and uncover new opportunities, ensuring that the firm remains a trusted partner in community-driven development.
