These are some of the businesses and individuals I work with and trust.
The DAGGER (Devonian Anoxia, Geochemistry, Geochronology, and Extinction Research) group is an interdisciplinary, international research team focusing on the systematics of mass extinctions in the Late Devonian.
We are based in Colorado, USA with offices in Westminster and Ouray. Our strategic locations allow close access to the USGS national core repository in Lakewood, fantastic outcrops in the Front Range and Wyoming, and the Book Cliffs of Utah.
Proximity to the field allows us to provide affordable, high-quality field trips to oil and gas professionals and students alike. Unlike many of our competitors we dont have to fly our instructor from the UK or Houston to Colorado. Our field office is located in picturesque Ouray, and it takes us less than two hours to get to the world-famous Book Cliffs.
Our mission is not to be the largest consulting firm, but to be your training and service provider of choice.
