Stith Keiser, Partner & Guide

When asked, “Why outfitting?”

Stith responded “I’m driven to the Wyoming wilderness each fall to experience the thrill and fulfillment that comes from watching a guest experience autumn in the Rocky Mountains, listen to the bugle of big bull elk and in the satisfaction that comes with doing everything I can to put them in a spot for a successful and ethical harvest.” I began my guiding career in Wyoming nearly two decades ago, and as an owner of Mountain Ivory Adventures, I’m excited to lend my experience and passion for outfitting and guiding to new and seasoned guests alike. I am also honored to share that same drive with our guides and staff who work to bring a memorable traditional, backcountry camp experience to our friends and clients who share in this adventure with us.

Nick Biermaier, Partner & Guide

Over the past 10 years, my focus has changed, from being the hunter to supporting the hunter. I have been hunting my entire life, guiding for the last handful of years, and now showing my kids what the outdoors has to offer. I am incredibly blessed at home with a beautiful wife and three healthy young boys. My wife is an avid hunter as well, so this entire business aligns with our family’s morals, ethics, and our faith background. I am looking forward to the adventure, and I cannot thank God enough for the opportunity to outfit and guide in the Gros Ventres.

Greg Armstrong, Partner & Guide

Greg has worn multiple hats for the outfit, from wrangler to guide. Growing up in the mountains of Idaho, western big game hunting is in his blood, and when he's not exploring the mountains with his family, he is passionate about providing a top-notch hunt and all-around experience for our guests.

Chuck Keiser

Chuck Keiser, DVM Partner & Wrangler

I became a partner in Mountain Ivory Adventures for several reasons. It combines my love of family, horses, the outdoors, and friends. The pleasure is indescribable that I get from taking people into the wilderness and showing them sights and giving them opportunities that few people ever get. Having a friend and client harvest an elk makes it an over-the-top experience! As I celebrate my 50th birthday for the 19th time, life doesn't get much better than this!

Wyoming Hunting Camp Kitchen

Camp Chef

Outfitters can’t control the weather or the animals, but we can control the cooking! Our seasoned Mountain Ivory camp cooks are responsible for providing hot, hearty and home-cooked meals to our guests. Mornings start with cowboy coffee, hot tea and a light breakfast enjoyed by a warm stove in our cook tent. After a morning of hunting, guests are treated to a large brunch with a menu ranging from homemade biscuits and gravy, to hot cakes, bacon, eggs and sausage, to breakfast casseroles. Dinners and desserts are varied and virtually guaranteed to leave you full and fueled for the next day's hunt! If you want to enjoy the Wyoming landscape with great people and good food, you will not be disappointed.
