Dr. Chriss Mack

 Dr. Mack started Bitterroot Bison in 2001. Alongside his busy Neurosurgical practice, his desire to raise animals lead to the natural choice of Bison. Raising bison became a respite from the demands of Neurosurgery. Dr. Mack then purchased 800 acres of land in Lolo and Stevensville and started the process of building the facilities and fencing to raise his bison. He purchased his bison from Hilda Thomas of the Bar-Z Ranch in Powel, Wyoming, known for her well-bred bison.  Secondarily, because of that expertise he hired Hilda to find the best breeding bulls available. Hilda then brought four breeding bulls home from Canada to Dr. Mack’s herd and Bitterroot Bison was born. In 2005-2006, Dr. Mack and Troy Westre teamed up which facilitates today’s Bitterroot Bison.

Troy Westre

Troy has been raising bison for 18 years. He does not come from a ranching background, but has developed a love for the lifestyle. He was a welder by trade and took up bison ranching as a hobby because he had “always liked the animal.” He wasn’t expecting to make a business out of it, but his herd kept expanding, and by 2005 he was looking for leased land so his business could continue growing. That year, a local bison rancher and surgeon, Chriss Mack, performed surgery on him. Troy noticed pictures of bison in Chriss’ office and discovered that he had a herd of his own. The two men decided to become partners, and they merged their herds onto Chriss’ land in the Bitterroot Valley near Missoula, Montana. Troy quit his job and dedicated himself fulltime to raising bison.  “I’m going on 18 years raising this magnificent animal. It has been challenging yet rewarding career. Not many people ever find their calling in life but I can say I have thanks to Family, Friends, Chris Mack and most important, the Bison.”

Ken has been helping on the ranch ever since. Ken says “Working with Troy and the bison through the years has taught me so much. I have been his right-hand man for almost 8 years.  I can’t wait to see what the future holds for us and the animal that I consider my spirit animal” Ken helps with everything from the food truck, to calving, to working the animals and much more.”
