TD2 was founded in 1967. We appreciate our past and look forward to Things 2 Come.

In 2017, TD2 celebrated our 50th year. What an amazing journey it has been working with the most creative and partnering clients. To mark our 50th year, we gifted 25 trees of native species to be planted in public/community spaces in both La Vista’s Thompson Creek Watershed and in Papillion’s Veteran’s Park to commemorate these long-standing relationships and to signify our commitment to stand with our clients far into the future.

Now in our 53rd year, we’ve been involved in the award-winning, highly-photogenic projects you can see on this site, as well as the development of many single-family and mixed-use neighborhoods in the Greater Omaha area. We call these Bread and Butter projects – those that accommodate our growing community and enrich lives. You can read more about them in our newsletters, and of course see what we mean in the gallery of Our Work. Whatever the size and scale of your project, the professionals of TD2 are here to help bring your vision to life.

Soils Laboratory – on-site soils analysis and reporting

UAV Unmanned Aerial Vehicle – In 2018 we added UAV capabilities and in 2020 have expanded aerial drone services with the purchase of a fixed-wing Topcon Sirius Pro and an additional copter. To give us flexibility and options depending on the project, the fixed-wing drone allows us to provide a variety of aerial services on large sites, over difficult terrains, and in windier conditions. The small copter will keep us flying on smaller, more congested sites.
