About Us

Putting and Keeping Kids and Wild Sheep on the Mountain!


Wyoming Wild Sheep Foundation’s mission is to conserve and enhance populations of bighorn sheep throughout Wyoming, to safeguard against their decline, and to fund programs for professional management of these populations, keeping administrative costs to a minimum.


Foster the conservation of healthy bighorn sheep populations, promote Wyoming’s hunting heritage, engage and educate citizens in scientifically sound wildlife stewardship, and encourage youth participation to ensure future conservation.
This vision is achieved through fundraising and educating public on issues affecting bighorn sheep, habitat, and hunting opportunities. We support strong science-based policies to retain and restore bighorn sheep habitats and sustainable funding for wildlife management. Our vision is brought to life by hunters and outdoor enthusiasts who recognize both the cultural and conservation significance of Wyoming’s bighorn sheep population.


Putting and Keeping Kids and Wild Sheep on the Mountain


The principles that guide us:
Honesty • Integrity • Respect • Teamwork • Positive Attitude
Respect for Wildlife • Hunting Ethics • Accountability • Stewardship • Advocacy • Loyalty


The Wyoming Wild Sheep Foundation (WY-WSF) was formed in 1983 and has a long record of actively working for the benefit of Wyoming’s bighorn sheep, healthy wildlife habitats, education, and hunters’ rights. Led by an all-volunteer Board of Directors, WY-WSF annually raises thousands of dollars through the energy and efforts of conservation-minded sportsmen and women. These dollars are put back on the ground through our Grant-in-Aid program to fund bighorn sheep population management, habitat restoration, disease research and surveillance, public outreach and youth education.

Katie Cheesbrough
Executive Director

Katie is incredibly grateful that her family moved to Wyoming when she was nine years old. As happens with so many who come to this state, she fell in love with the landscapes, the wildlife, and the people. Through the outdoor adventures of a kid growing up in Wyoming, Katie was inspired to pursue an education and career in wildlife biology. After receiving her Master’s from the University of Wyoming, Katie continued her lifelong love of wildlife working as a wildlife and habitat biologist for several organizations, including the US Forest Service and the Wyoming Game and Fish Department. However, Katie now counts herself lucky to serve as the executive director of the WY-WSF. Here, she and her family have found a home amongst Wyoming’s most dedicated, passionate, and fun-loving wildlife advocates and sports people. Together with the WY-WSF Board of Directors she now leads the foundation onwards and upwards by coordinating with Wyoming’s natural resource agencies, serving on the Statewide Bighorn/Domestic Sheep Interaction Working Group and advocating for bighorns and other wildlife.

Dean DiJenno
Deputy Director

Dean gained his appreciation for nature as a youth by hunting and fishing with his family. After joining the Boy Scouts of America, he had the opportunity to attend Camp Philmont in New Mexico and his destiny to live in the West was sealed. Moving to Wyoming in 1973, he quickly began a love affair with the Wind River mountains where he learned to hike, climb, photograph and study wildlife. After his first trip to Whiskey Mountain where he saw bighorns walk all around his car, he was bitten by the wild sheep bug. He completed a career of 36 years with the Postal Service where he learned the administrative skills that he uses today to keep the chapter paperwork on track. After his first retirement, he and his wife, Diane, found their true calling, and a large circle of new friends when they joined the WY-WSF in 2011. Dean is a Ron Ball award winner, a former board member and now serves as deputy director of the foundation. His duties include administrative work, editing the RamPage, webpage and assisting the executive director and board members with their workloads.
