Learn Who We Are

  • Dr.
    Severin Knudsen

    Dr. Knudsen was born and raised in Portland before heading to the East Coast for his higher education. After graduating from Veterinary School at Virginia Tech he moved to Boise, Idaho where he has practiced both large and small animal medicine for the last three years. Although he finds beef production to be one of the most rewarding parts of his job, he also will admit to a big soft spot for cats. Enterprise has always been a dream location for both Severin and his wife, Emily Knudsen. Severin and Emily are outdoor enthusiast and look forward to enjoying all the great hiking, climbing, fishing and hunting that Wallowa County has to offer. When not found at home curled up with his wife and three cats, you are most likely to find Severin hiking the hills looking for Chukar with his Brittany pup, Ranger.
