Tjornehoj & Hack LLC

Tjornehoj & Hack LLC was founded by Jon Tjornehoj in 2007, after concluding five years of practice in the natural resources department of a large Denver law firm. Originally under the name Jonathan D. Tjornehoj, LLC, the firm began as a solo title practice focused on Colorado's Denver-Julesberg Basin and Wyoming's Pinedale Anticline. Jon's practice involved not only rendering title opinions, but also curing title defects over large federal units and conducting stand-up title examination. It was in those early years of digging up documents in the back rooms of Clerk and Recorders' offices and tracking down predecessors in title to execute curative that Jon came to understand title from a landman's perspective. That perspective is instilled in the firm today.

In 2010, Jon was joined by his former colleague, Peter Hack. Peter and Jon had previously worked together for several years on a host of natural resource issues, including public lands litigation and oil and gas transactions. In 2013, the firm formally changed its name to Tjornehoj & Hack LLC.

Expertise from the Ground Up

Tjornehoj & Hack LLC was born out of a mineral title practice focused on oil and gas development in Colorado's Denver-Julesburg basin. Because mineral title examination provides the basic legal foundation for the acquisition and development of energy resources, we developed an intricate understanding of each legal phase of the energy development process. As we expanded, our clients called on our firm for assistance in transactional, compliance and litigation matters. From exploration and initial test wells, through full-field development, secondary recovery and asset transfer, our mission is to partner with clients and seek out resourceful solutions to the challenge at hand. We assist clients in maximizing the opportunities presented by energy development in the modern setting. We are proud of the excellent work we are a part of on projects throughout Colorado, Wyoming and North Dakota, assisting clients in reaching their goals in the Denver-Julesberg Basin, the Bakken Field, the Piceance Basin, the Powder River Basin, and beyond.

Energy for Today and Tomorrow

Our firm is rooted in the Rocky Mountain west and we believe that mineral development is an intricate part of our community's past and future. Mineral and land owners play key roles in that development. Application of new technologies has brought renewed economic prosperity to Colorado, Wyoming and North Dakota. Through good times and bad, mineral and land owners need flexible tools to manage the present and plan for the future. Our estate planning practice helps mineral and land owners realize their goals for this generation and next. We are proud to be a part of making that opportunity a reality.
