Stacy Kourlis Guillon

Aegis ADR

Stacy is originally from Craig, Colo., where her family had a sheep and cattle ranch. After graduating from Dartmouth College and working on litigation policy issues in Washington, D.C., Stacy attended graduate school at Stanford University, where she earned her law degree as well as her M.S. in land use and agriculture. When Stacy and her husband, Ben Guillon (who also works with ranchers and other landowners as a conservation investment advisor), moved back to Denver, Stacy began her legal career as a clerk for the Honorable Judge Timothy Tymkovich of the United States Court of Appeals for the Tenth Circuit. She then joined the law firm Lewis Roca Rothgerber Christie, where her practice focused primarily on agricultural clients.

For the farmers, ranchers, agribusinesses, and other agricultural professionals she represented, Stacy engaged in a wide range of litigation, including land use, federal grazing, probate, and commercial disputes. Now, Stacy serves as an arbitrator and a mediator at Aegis ADR, helping to resolve the legal disputes of a wide variety of clients, including those across the agriculture industry. Stacy is also involved in several agricultural nonprofits, including as a board member of the Colorado Cattlemen’s Agricultural Land Trust, and she is a trustee of the National Western Stock Show. She also serves as a member of the Corporate Council for Inclusion and Diversity for the College of Agricultural Sciences at Colorado State University.
