Kevin Hurley, Vice President of Conservation – Thinhorn Programs
As Vice President of Conservation – Thinhorn Programs for WSF, Kevin Hurley brings 48 years of experience as a wildlife biologist, with wild sheep, particularly bighorn sheep, being a huge part of his personal and professional life for the past 44 years. Prior to joining WSF’s staff in February 2011, he spent three decades as a wildlife biologist for the State of Wyoming Game & Fish Department (WGFD), retiring as the statewide bighorn sheep program coordinator. During his final years working for WGFD, Kevin chaired the Wild Sheep Working Group for the Western Association of Fish and Wildlife Agencies and has remained an active member representing WSF for the past 13+ years. During his career with WGFD, he survived two plane crashes (Dec. 1991 and Aug. 2002), both while surveying pronghorn. The resulting injuries changed his life: While not able to physically do the things he had done before, he learned to compensate with a tireless work ethic as a wildlife professional.
Dedicated to the future of wild sheep, Kevin completed his $100,000 commitment as a WSF Marco Polo Society member (#24).Kevin has been a WSF member since 1981, became a Life Member (#794) in 1997, and a Summit Life Member (#23) in 2014. Kevin is currently a proud Life Member of 21 WSF Chapters & Affiliates. His allegiance to WSF began in his college years—using proceeds from the Wyoming Governor’s bighorn sheep licenses, FNAWS (later WSF) was the major funding source for his graduate studies at the University of Wyoming, where he studied the Trout Peak bighorn sheep herd, located between Cody and Yellowstone National Park.
In his hunting life, Kevin fired his first gun when he was 25 years old. In a bit of a twist on typical situations, Kevin was mentored by a younger buddy (and lifelong friend!) and learned how to hunt after moving to northern Idaho in 1978. He later went on to earn his FNAWS by taking a Wyoming bighorn sheep in 1997; an Alaskan Dall’s in 2011; a Yukon Stone sheep in 2012; and a southern Baja desert ram in 2014. Kevin notes that he had his only son Kyle with him on three of his four successful ram hunts. Today, Kyle is a mechanical engineer, accomplished archer, WSF Summit Life Member, and Life member of the Idaho, Wyoming and Yukon Chapters of WSF. Kevin accompanied Kyle on two successful hunts wild sheep hunts, in fall 2017, for Dall’s sheep in the Yukon, and Coahuila, Mexico for his desert ram. Kevin is one proud grandpa, as Kyle and his daughter-in-law Tess have two young sons (Jaxon, Remington), both already WSF Life Members. In October 2023, Kevin married Connie Sturdavant, and they live a happy life together near Boise, Idaho.
Kevin truly believes in “paying it forward” and being loyal to those that helped him in his wild sheep career!

Kim Nieters, VP of Operations & Auction Director
A proud Life member of WSF, Kim has spent over 30 years working for the Foundation. At the age of 20, she began her career at WSF (then known as FNAWS) as membership coordinator. Ever since then, she has found the driving force behind her professional passion has always been WSF’s energetic and inspiring members. As Kim always says, “I work for them”.
During her WSF tenure, she has helped manage the Foundation’s membership, merchandise, raffles, awards, and auctions and has recently been promoted to VP of Operations. This new position gives Kim the opportunity to learn more about the Foundation at a higher level and foster relationships with her fellow team members.

Keith Balfourd, Director of Marketing & Communications
Balfourd has spent the past 18 years as Director of Marketing for the Boone and Crockett Club.
“Keith has been a friend to our conservation community and WSF for many years,” said Gray N. Thornton, President and CEO of the Wild Sheep Foundation. “He’s as well respected, talented and dedicated as they come. We’re thrilled to have Keith join our team.”
Balfourd has worked within the hunting, angling, and conservation arena for the past 28 years in various capacities as an outdoor communicator, marketer, publisher, television producer, instructor and guide. He currently resides in Florence, MT with his wife and two daughters.
“I’ve been fortunate to be able to turn my passion for wildlife and the outdoors into my life’s work, which has taught me a lot,” Balfourd explained. “One thing I do know is that we would not have wild places, wild things, and the opportunity to hunt today if it were not for Theodore Roosevelt and the Boone and Crockett Club. It was both an honor and a privilege to be a part of this legacy, and the work the Club is doing today. The best one can hope for in this business is to be able to make a difference. I feel like I’ve been able to do that with B&C, and look forward to doing the same at Wild Sheep. Both organizations are at the forefront at what lies over the horizon for conservation.”
Paige Culver, Development Manager
Paige and her family reside in Bozeman, MT. As they enjoy all things outdoors, it only makes sense that they place conservation at the core of their value system. Being avid hunters, Paige and her husband spend many of their “dates” scouting and tracking down big game with bow or rifle in hand. She works hard to teach her two children how to be good stewards of all that they have been given and to give back when able. She has recently made it a goal to join, and ultimately be kicked out of, the <1 Club.
Paige has a Bachelor’s of Science degree in Business Management and a minor in Corporate Communications and brings knowledge from various career experiences. Prior to joining the team at WSF, she worked as a program manager for Montana State University and also owned and managed a rodeo apparel company. Her experience owning and operating her own business gave her a wealth of experience in networking, marketing, and operations management as well as an extra helping of grit. As Development Manager, Paige looks forward to helping continue the legacy WSF has created in making great strides for the conservation of wild sheep.
Terry Ziehl, Finance Manager
Terry was born and raised in Cloquet, Minnesota, which is about 20 miles from Duluth. Her father did a little bit of hunting, but his passion was fishing and camping at Leech Lake. As a family, they used to always say, "if you wanted to go fishing with dad, you better want to stay out there for hours!" So naturally, Terry grew up fishing, which she still loves to do today.
In 1981, Terry married her high school sweetheart, Terry (yes, they have the same name). They soon moved to Casper, Wyoming so he persue a degree in the oil field. After obtaining his degree and a position with Marathon oil, the Ziehl's were transferred to Cody in 1986. Terry became familiar with FNAWS while she lived in Casper since her husband was a member. Terry started with WSF back in 1987 as a part time receptionist. "I guess you could say I really enjoy working here 30 years later!" she says.
Terry has worked almost all positions, except graphic design. She wears many hats here at WSF world headquarters but her main job is in account receivables and payables. Terry especially looks forward to the convention each year! She loves to catch up with the many friends she has made and to always make new ones!
Terry has two girls; Sami, the oldest, lives in Cody. Kimberly, the younger daughter, currently lives in Billings, Montana.

Jaime Teigen, Administrative Assistant
Chef Jaime grew up in northern Idaho where her love for the outdoors flourished with skiing, camping, fishing with her dad and grandpa, and playing ghosts in the graveyard with the neighborhood kids. She grew up at a house that everyone came to, so with that, there was always food around. Her mother is an exceptional cook, and her dad has always been the grill master. It wasn’t until after high school, that her curiosity about food really came to life. She went to Western Culinary Institute in Portland, OR, then went on to be an Executive Chef in Portland, and then moved to Jackson Hole, WY to do the same. That is where she met her husband, Caleb, and began her journey with field to table and learning the whole process of truly knowing where your food comes from and sharing that with others. Jaime currently is a freelance chef, an instructor for wild game cooking for OutdoorClass (an e-learning platform for hunters and outdoorsmen/women), an Ambassador for Montana Wildlife Federation, the new chef for Carnivore’s Kitchen for RMEF, and works for Wild Sheep Foundation as their Administrative Assistant.

Serving WSF for the past 11 years as its youth education coordinator, Ryan grew up learning to love the great outdoors in southern Colorado, where he spent summers exploring the wildlife refuges where his father worked. Through various backpacking and horse-packing trips with his family when he was young, he learned about the natural world. An avid hunter, today he enjoys pursuing big game and birds.
While focusing on science education, Ryan earned a master’s in education and a Ph.D. in curriculum, teaching and learning. His dissertation was dedicated to further understanding the timeframe youth take to develop an environmental identity to the natural world while participating in after-school nature clubs.
During his tenure for WSF, he has led the Youth Wildlife Conservation Experience (YWCE) as a component of the WSF Sheep Show® in Reno. He also spearheads WSF’s nationwide Shooting, Hunting & Ethics Education Programs (S.H.E.E.P.), where Ryan conducts youth outdoor outreach for WSF Chapters and Affiliates and teams up with other nonprofits, such as Ducks Unlimited and the Rocky Mountain Elk Foundation. Both YWCE and S.H.E.E.P. offer youth exciting exposure to shooting, archery and hands-on learning about wildlife, habitat and conservation. Attendance has grown exponentially for WSF youth events over Ryan’s tenure.
In addition to his part-time work for WSF, Ryan has taught 25 years in upper elementary classrooms and is currently a fifth grade teacher in Reno, Nevada. Beyond his professional life, he continues to inspire his son and young daughter to cultivate curiosity and excitement about the natural world.
