Lawyers Who Know the Land in the Rocky Mountain West

Our firm was founded by natural resources lawyers.  From our original core practice focusing on the exploration and development of energy resources, mining, and public lands, we have grown a broad set of skills to navigate all aspects of land and mineral management. We bring that experience to bear by partnering with each client to seek out pragmatic solutions for the development and preservation of their assets. Whether you need to sort out an intricate web of legacy title problems, require assistance structuring a transfer of property interests, or want to secure your lands for future generations, we have the skills to help you find the best way forward.
