Dr. Trevor McCormick

Veterinarian/Clinic Owner

Dr. Trevor McCormick grew up in Phoenix, Arizona, where his father, a native of Livingston, Montana, practiced equine veterinary medicine and surgery. He spent summers in Livingston visiting family and enjoying this beautiful state. In 1998, after his first year at Arizona State University, he moved to Montana where he completed his undergraduate degree in Biotechnology of Animal Systems at Montana State University.

Dr. McCormick has always had a love for animals and the bonds we share with them. During his time at Montana State University, he volunteered for Great Plains Assistance Dog Foundation and their puppy-raising program, earning the nickname on campus as “the guy with the dog.” His fascination with biology and physiology made veterinary medicine the perfect career choice.

In 2006, Dr. McCormick graduated from Washington State University College of Veterinary Medicine, earning the Pfizer Animal Health Veterinary Proficiency Award. Eager to return to Montana, he began his career in Three Forks, Montana, at a mixed animal practice. He later decided to leave the practice and work as a relief veterinarian practicing in over 20 different clinics across the state. Finally, Dr. McCormick returned home to Livingston where he has been working since. In August 2016, he started his own practice, Sleeping Giant Animal Clinic.

Believing in the need to stay current with ever-changing medical knowledge, Dr. McCormick has attended numerous continuing education conferences surpassing the state requirements for maintaining his license. Dedicated to the profession and the pursuit of knowledge, he accepted a nomination to the board of the Montana State Veterinary Medical Association in 2013 completing his term of service in 2020.

Dr. McCormick also works with veterinary students and technicians from all over the country at his clinic where he dedicated an apartment for students to live in while getting practical experience. In 2018 and 2019, he volunteered with World Vets and traveled to Siem Reap, Cambodia, to perform sterilization surgeries and provide general health care for dogs and cats. Dr. McCormick also instructed veterinary students from the Royal University of Phnom Penh on surgical techniques during the project.

Dr. McCormick’s professional interests are focused on enhancing the human-animal bond, reducing stress and anxiety in animals during veterinary visits, internal medicine, soft tissue, and orthopedic surgery, and most recently utilizing ultrasound as a diagnostic tool. Dr. McCormick’s wife, Courtney McCormick, helped establish their business and facilitated the construction of their permanent facility, completed in October 2017. Their two teenage children, Lyle and Jorja, share a strong interest in the veterinary field and routinely assist in patient care and emergencies. Their family also includes four dogs, three cats, a hedgehog, three horses, and chickens. In his free time, Dr. McCormick enjoys gardening and spending time with his family in the outdoors fishing, hiking, and camping.
