Dr. Greg Clausen Greg didn’t always know he wanted to be a veterinarian, but has been largely influenced by his experiences on the family farm in Fairfield. After all, it was there that Greg developed his respect for manual labor and his love for beef cattle, but also where he learned the finer skills in life like how to make a good pie. His grandmother never cut corners; she still tends to the garden, makes a pancake breakfast every morning, and delivers root beer floats to the boys on hot summer afternoons of harvest season. This work ethic continues to motivate Greg.

Inspired by his sister, Greg considered a career in genetic research. He studied Biology and Chemistry and completed a genetics based honors thesis and publication while attending Carroll College. But after heavy deliberation, Greg realized he wanted more from life than grant proposals, committee meetings, and peer reviews.

During his first year in Oregon, Greg became familiar with the staff, students, and curriculum at Oregon State University and encouraged by his wife, decided to pursue medicine. Once enrolled, he thought surely he would find himself working by way of flashlight at 3 am on the coldest days of the year; bovine medicine was all he had really ever known. But it didn’t take long for Greg to discover a new passion - radiology. Still, Greg couldn’t completely dismiss his previous aspirations. In addition to his regular studies, he found a way to combine his long time admiration for cattle and the uncharted territory of imaging, completing another research project eligible for publication.

After graduation and while pursuing his interests in radiology, Greg completed a small animal rotating internship at Auburn University and has since shifted his focus to companion animal medicine. Like Misty, Greg couldn’t wait to return to Montana where he continues to enjoy the challenges of radiology and internal medicine.

Greg has been described as competitive, passionate, determined, and curious. Greg is committed to providing the best medicine he can for his patients and is dedicated to expanding his knowledge to remain on the forefront of care. He believes that there is something to be learned from every case, regardless of how routine it may seem. And although the path to this point was long and imperfect, the destination has been worth the journey.

Dr. Misty Clausen Misty has always found comfort in the quiet calm that comes from the company of animals. As a child she was drawn to shows like David the Gnome and ER Vets, and as she grew so did her desire for the vet life. While many other children had a revolving answer for the age old question “what are you going to be when you grow up”, Misty never doubted her purpose. But the road to becoming a veterinarian is hard and how was a child of humble beginnings going to get there? One word: determination. Motivated by the advice that being happy requires being brave enough to listen to your heart, Misty became the first in her family to go to college. She studied Biology and the human-animal bond at Carroll College and considers her time there to be some of the most inspired years of her life. She forged lifelong friendships, met her husband, and found her appreciation for canine behavior and training.

After Carroll, Misty spent 3 years as a veterinary assistant, developing technical skills to compliment her academic knowledge in preparation for vet school. More importantly, this experience led to her philosophy that exceptional care takes more than great doctors and fancy equipment, it requires a team of compassionate people all dedicated to patient comfort and the understanding that no one is above getting their hands dirty. It was also during this time that Misty met her mentor who continues to inspire her to never stop learning and growing, personally and professionally.

Misty attended Oregon State University and although she studied both large and small animal medicine, she has always had an affinity for companion animals. As she moved through those four years, her interests continued to diversify. Along with behavior, Misty developed a passion for preventative medicine, dentistry, and reproduction. But despite its beauty, Oregon never felt like home and Misty was happy to return to Montana to continue practicing medicine.

The people closest to Misty describe her as genuine, compassionate, honest, and hard-working. But perhaps her most notable quality is humor. She’s quick witted, talks to animals as if they will suddenly talk back, and finds that making people smile is the gift that keeps on giving. Misty considers her dogs to be more than pets, they are family. What Misty admires most about animals is that they will never try to fix you with words; instead they are content to sit with you in the dark until you find the light.
