The conservation community of the American West lost one of its brightest lights in March 2026 with the passing of Cheyenne Gililland. Serving as the Philanthropy Director for Colorado Trout Unlimited (CTU), Gililland was far more than a fundraiser; she was a visionary connector who wove together the passions of people with the urgent needs of the natural world. With a career spanning nearly two decades, her life was a testament to the power of authentic relationships, environmental stewardship, and a boundless love for the outdoors.
Early Life & Education
Born and raised in Austin, Texas, Cheyenne’s profound appreciation for the natural world was cultivated early. Whether she was hiking scenic trails, getting her hands in the dirt, or simply observing the quiet beauty of a flowing stream, she recognized from a young age that nature was a sanctuary worth protecting.
This deep-seated passion guided her academic pursuits. She attended the University of Texas at Austin, where she earned a bachelor’s degree in Geography with a specialized focus on Natural Resource Management. This educational foundation provided her with the scientific and geographical context needed to understand complex environmental challenges, shaping a career that would seamlessly blend ecological advocacy with human connection.
Career & Contributions
Gililland’s professional journey was defined by a nearly 20-year commitment to philanthropy, land and water conservation, and historic preservation. In Texas, she honed her leadership and strategic skills by serving as the Director of Development at the Hill Country Conservancy in Austin and the Cibolo Center for Conservation in Boerne. In these roles, she successfully drove initiatives that preserved vital landscapes and expanded environmental education.
Upon moving to Colorado, her impact only magnified. Before joining CTU, she served as a Philanthropy Officer for Colorado Open Lands and History Colorado, advocating for both the state’s ecological heritage and its cultural history.
Her career reached its zenith when she was appointed Director of Philanthropy at Colorado Trout Unlimited. At CTU, Cheyenne played a pivotal role in advancing the organization’s mission to protect, reconnect, and restore the state’s coldwater fisheries and watersheds. She approached philanthropy not merely as a transactional necessity, but as an opportunity for profound community building. She was instrumental in managing exclusive donor initiatives, such as the River Champions Circle, which provided supporters with tangible connections to their conservation investments through on-the-water experiences and stream restoration projects. Through her tireless efforts, critical projects aimed at preserving waterways and restoring native fish habitats received the vital funding they needed to succeed.
Leadership & Affiliations
Cheyenne’s expertise extended far beyond her day-to-day professional duties. She was an authoritative voice in the nonprofit sector, widely respected for her strategic vision and her ability to cultivate genuine, lasting partnerships.
Her leadership was equally felt in her volunteer affiliations. Dedicated to holistic community enrichment, she served on the Board of Directors for A Child’s Song, a Denver-based organization dedicated to changing lives through music. Furthermore, her philanthropic reach was global; she was actively involved with Lalmba, an organization that provides life-saving medical services and empowerment opportunities to rural communities in Ethiopia and Kenya.
Colleagues and partners consistently noted her vibrant personality, describing her as a compassionate, driven leader who uplifted everyone around her. At CTU, she worked closely with Executive Director David Nickum and a passionate team, bringing an infectious optimism and momentum to every initiative she touched.
Legacy & Impact
Cheyenne Gililland passed away in March 2026, leaving an indelible void in the hearts of her colleagues, friends, and the broader conservation community. She is survived by her partner, Chad, her beloved Bernedoodle, Ernie, and a wide network of family and friends who cherished her joyful spirit.
Her legacy is inextricably linked to the landscapes she fought so hard to protect. It flows through the restored trout habitats of the Rocky Mountains, the preserved open spaces of the Texas Hill Country, and the countless individuals she inspired to become stewards of the earth. As tributes poured in following her passing, a common thread emerged: Cheyenne had a unique gift for making people feel valued and connected. It was, as one tribute noted, “impossible to not smile” in her presence.
While her time was cut tragically short, Cheyenne Gililland’s life remains a powerful narrative of purpose. She demonstrated that true conservation is about more than just protecting natural resources; it is about nurturing the human connections that make such protection possible. Her work will continue to sustain Colorado’s rivers and inspire future generations of environmental advocates.
