About COGA
Our team of experts and executive board are dedicated to championing industry, leading advocacy, and building community in the state of Colorado.
Letter from the CEO
In Colorado, we are leading the way in delivering energy that is reliable, affordable, and produced with care. Oil and natural gas have long been essential to our state’s economy, communities, and daily lives. Today, thanks to innovation and a steadfast commitment to safety and sustainability, our industry is producing energy cleaner and more responsibly than almost anywhere else in the world.
I am honored to lead an organization that stands at a pivotal moment—facing both unprecedented challenges and exciting opportunities. Our mission is clear: to champion the responsible development of oil and natural gas resources in Colorado through effective and meaningful engagement with communities, policymakers, and regulators. When our industry succeeds, so do our communities.
At COGA, we are grounded by core values that guide our approach: integrity, respect, collaboration, excellence, education, and resilience. These principles shape how we advocate, communicate, and lead on behalf of our members and stakeholders. We serve as a trusted source of fact-based information and thoughtful leadership in legislative advocacy, regulatory oversight, community engagement, and workforce development.
As we advocate for the industry, we are also preparing for its future. That means addressing key challenges like permitting reform, regulatory overload, and public perception. Our vision is to lead the oil and gas industry in building a resilient energy future—one that balances environmental responsibility with the energy needs of today and tomorrow.
Colorado’s oil and gas sector supports thousands of jobs, fuels our state’s economy, and provides critical funding for schools, infrastructure, and public services. At COGA, we are committed to preserving and advancing that legacy through proactive, thoughtful, and transparent advocacy.
Whether you are a policymaker, a community leader, an industry partner, or a concerned citizen—there is a place for you at COGA. Together, we can ensure that the responsible development of Colorado’s natural resources continues to benefit our state for generations to come.
Thank you for your support. I look forward to the journey ahead and to working together toward a stronger, more secure energy future for Colorado.

COGA chapters provide an expanded statewide presence for the industry and the association. Activities include hosting fundraisers and making contributions to local civic and charitable causes, working in and with local schools, assisting at community functions and providing scholarships. With a membership of local industry employees, each chapter operates independently, but under the authority and direction of the COGA Board of Directors.
