Hamish Williams, Executive Director
Hailing from a small village on the outskirts of London, Hamish started his outdoor journey rambling through the English countryside surrounding his childhood home. He was fortunate to be raised by two ski crazed parents who carried him around the mountains until he learned enough to keep up with them on the icy slopes. The Alps whet his appetite for big adventures, and during the non-winter season Hamish spent his time planning future mountain escapades and dreaming of wilder and wilder places. This journey eventually took him to the Western U.S. where he found big mountains with very fluffy snow.
Hamish is a big believer in outdoor accessibility for all, and has made it his life’s work to get everyone he meets to engage in outdoor recreation in some capacity. He has a background in facilitating intentional therapeutic outdoor experiences, and believes that though humanity has evolved to avoid many of the difficulties that a life outside previously presented to us, we haven’t moved beyond our intrinsic need to connect with the natural world. He has a passion for trauma informed care and the reduction of childhood adverse experiences and believes in the power of leveraging experiences during the formative years of our lives to find connection and help break the chain of generational trauma.
When he isn’t spending time scrambling, climbing, or otherwise playing in the Wasatch Mountains, Hamish likes to cook, make things, and spend time with his partner Carly and their dog, Hugo.

Keldon Joyner, Development Director
Keldon Joyner is the Development Director for Wasatch Mountain Institute, where he channels his passion for outdoor education, equity, and environmental stewardship into creating opportunities for underserved communities. With a background in non-profit leadership and small business management, Keldon works to expand WMI’s reach and impact, ensuring that every child in Utah has the opportunity to experience the transformative power of nature. Originally from Bozeman, Montana, Keldon grew up immersed in the Rocky Mountains, skiing, backpacking, and exploring the outdoors. His love for nature was matched by his dedication to giving back, whether through maintaining local trails, landscaping with native plants, or fostering a strong sense of community.
In 2024, Keldon moved to Salt Lake City and quickly found inspiration in the stunning landscapes of the Wasatch Front and Back. When he’s not focused on advancing WMI’s mission, Keldon enjoys hiking, camping, and discovering new places to explore in Utah’s vast wilderness. He is deeply committed to making outdoor experiences accessible to all, believing that nature has the power to inspire, connect, and empower.
Abigail MacKay, Program Manager
Abigail was born and raised under the shadow of the Wasatch Mountains in Murray, UT. As a child, she developed an affinity for the natural world and took her Junior Ranger oath to protect and preserve the lands to heart. During her time as a college student at Utah State University, Abigail realized that she wanted to help young people have the same experiences that had led her to her degree in Environmental Studies. She decided to pursue a Masters of Science in Environmental Science with a certificate in Environmental Education and Science Communication from the University of Idaho’s McCall Outdoor Science School.
In addition to her studies at the University of Idaho, Abigail was awarded a research assistantship in the CIRCLES Scholars Program. Abigail’s research focused on bridging the gap between Indigenous students and STEM programming. As a proud Kanaka Maoli (Native Hawaiian) this research deeply impacted her and her goal of making the outdoors more accessible and inclusive for all.
At WMI, Abigail helps students get outside by making sure programs are running smoothly and developing curriculum that is engaging, dynamic, inclusive, and most of all fun.
She loves being home in the Wasatch and exploring the mountains with her husband through all kinds of weather and recreation.
