Meet Our Doctors

  • Mike Cohn

    He was born in Lawrence, Kansas and raised in Prairie Village, Kansas. A profound love of animals and no such thing as a routine day led him to choose veterinary medicine for a career. He attended vet school at KSU and graduated in 1988. On August 8, 1988, Dr. Cohn arrived in Idaho to work with small animals in clinics from Nampa to Boise. Idaho presented many outdoor activities that were close including skiing, hunting, fishing, hiking and white water rafting.

    In order to expand his horizons and help animals in need he worked 2 years at the humane society. The 2 years of service provided many lessons, the most important being that 90% of the animals at the 'pound' were there because of behavior problems. On May 3, 1993 the Critter Clinic opened focusing on preventive medicine from spaying and neutering to behavioral issues from puppies and kittens to the geriatric pets and their individual needs.

  • Fiona Thresher

    Dr. Fiona Thresher grew up, until the age of eleven, in East Africa surrounded by animals and knowing they would always be a large part of her life in one form or another.

    After finishing High School in the British system, her parents returned to the United States just as she entered college. While getting her Bachelor's Degree in Biological Sciences, she spent the summers working with a Veterinarian in Bellevue, Idaho in his mixed animal practice. Dr. Thresher attended Veterinary School at the University of California Davis where she graduated in 1992 with an emphasis in Exotic Medicine. In 1993 she married her college sweetheart and began her career working at the Humane Society of Santa Clara County, helping to set up their pre-adoption vaccination program and their health and behavior evaluations.

    In '96 Dr. Thresher joined a private practice doing small animal medicine and surgery as well as working with local wildlife and continued working there until leaving California with her family in 2001.

    Dr. Thresher enjoys working part time and doing relief work. Her hobbies include traveling, gardening, camping, fly-fishing, skiing and enjoying the many outdoor activities of Idaho with her husband and boys. She met Dr. Cohn and started working at Critter Clinic November of 2002.
