Kevin Hurley

Kevin Hurley, Senior Conservation Director, THS PROGRAM LEAD

As Senior Conservation Director for WSF, Kevin Hurley brings over 40 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 36 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 six 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, he 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 fourteen 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. He 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 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 U. Wyoming grad, mechanical engineer, accomplished archer, WSF Summit Life Member, and Life member of both the Idaho and Wyoming Chapters of WSF.Kevin will be accompanying his son Kyle on two hunts in fall 2017, for Dall’s sheep in the Yukon, and for mountain goat in British Columbia.

Terry Ziehl

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.


Kim Nieters

Kim Nieters, Auction/Awards Manager

A proud Life member of WSF and a new <1 Club member, Kim has spent nearly 30 years working for the foundation. At the age of 20, she began her WSF 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. With the generosity of WSF’s donors/exhibitors/sponsors and members, Kim and WSF’s stellar staff have raised over $110 million to benefit wild sheep and their habitat. Working for WSF has been the best education in the world, Kim says, teaching her professionalism, values and the principles that guide her every day.

Kim began hunting just a few years ago and fell in love with bird hunting, then took her first big game animal on a 2015 antelope hunt with the help of her friend and former WSF staff member Justin Phillips. She plans on trying for another buck antelope this fall. 

Kim has two beautiful daughters, Shelbie and Emma, and a grandson Zavier, her biggest fan. Kim spends her leisure time taking them camping and traveling with them on sports outings.

She celebrated many birthdays in hunting camp and received her first gun on her 12th birthday during a moose hunt in Cokeville, Wyo. She killed her first deer at 13. In 2015, after living her whole life in a state with more antelope than people, she finally harvested her first antelope with the help of fellow WSF staff members Kim Nieters and Justin Phillips.

Sam Sposito

Sam Sposito, Administrative/Membership Assistant

Sam Sposito grew up in Northern California where she was exposed to hunting and fishing at a young age.  Her father and older brother were both dedicated waterfowl and deer hunters and frequented the Sacramento river in search of stripers.  Having been raised around horses, rodeo, hunting and fishing Sam gained an appreciation for animals and the outdoors that she now values for her own children.  Due to her husband’s involvement in the hunting industry Sam began attending the WSF show in Reno, first as an attendee then for numerous years as a volunteer.  It was from here that she spawned an appreciation for conservation and for the WSF family and brand.  Sam and her husband Jeff have two daughters, Taylor and Ryan.  They have now lived in Montana for a handful of years and appreciate all the outdoor activities Bozeman has to offer their young family.  From 4-H to hunting and fishing or camping and skiing Sam stays busy raising her family the way great mom’s do.

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 Affliliates and for other nonprofits, such as Ducks Unlimited and the Rocky Mountain Elk Foundation. Both YWCE and S.H.E.E.P. offer school kids 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.
