Jon Tjornehoj brings to the firm 20 years of experience practicing natural resource law. After completing law school at the University of Wyoming, Jon began his career at a major Denver law firm litigating federal public lands matters. That litigation background focused on NEPA compliance and FLPMA land planning disputes relating to energy development projects in Wyoming. Jon’s experience there later revolved around oil and gas asset transactions and title examination.
In 2007, Jon began his own practice dedicated to title examination and title curative preparation for oil and gas assets. For fourteen years Jon built and managed the firm eventually known as Tjornehoj & Hack LLC, one of the region’s largest practices focusing exclusively on mineral title issues. The attorneys at Tjornehoj & Hack LLC collectively examined title to hundreds of thousands of acres across Colorado, North Dakota, Texas and Wyoming. Jon also served as an expert witness in a number of royalty dispute cases.
Jon is currently a Member of Tjornehoj Hack & Lovell LLC where he specializes in complex title matters including federal exploratory units, secondary recovery units and energy development projects in urban interface areas. He takes great pride in producing a title product that is not only thorough and precise, but which communicates issues clearly and presents pragmatic and innovative solutions. He believes that title opinions should not be filled with legal jargon and unrealistic requirements. Rather, a good title opinion assists the client in identifying and assessing risk, and anticipates the challenges of title curative from the client’s perspective.
