Dr. Clancy Mortensen

Veterinarian

I am from Fillmore, Utah. Growing up, I developed a great love for the outdoors. I enjoy hunting, fishing, camping, and many other outdoor activities. I went to Millard High school and was involved in several sports such as football, baseball, and wrestling. I then served a 2 year LDS mission to Alabama. After returning home, I attended Snow College for 1 semester before transferring to SUU for the remainder of my undergraduate education. I was then accepted into the WIMU (Washington, Idaho, Montana, Utah) regional veterinary program. My first two years of vet school were in Logan, Utah at Utah State. I then moved to Pullman, Washington to finish vet school at Washington State. I am very happy to be working here at Dixie Vet Clinic. I am excited to be able to serve the people and animals here in this area.


Dr. Susan McDonald

Veterinarian

Dr. Susan McDonald earned her DVM degree in 1984 from Colorado State University.  She practiced 34 years in northern Utah,  primarily in Salt Lake City.  In April 2018 she retired and she and her husband moved to St George, a long awaited dream of theirs to get out of the snow.  Retirement didn’t last long as she started doing relief work for Dixie Veterinary Clinic in September 2018, and after her husband passed away she joined the clinic as a regular part time clinician.  Her special interests are internal medicine, nutrition, and pain management.  When not working she enjoys gardening, playing piano, and hiking with friends and her dog Zeke.
