veterinary medicine. Dr. Holbrook earned her Bachelor’s degree in Environmental Health with a minor in Business Administration and Doctor of Veterinary Medicine from Colorado State University, graduating from veterinary school in 2020. During vet school, she also completed graduate-level coursework in public health and data analysis and assisted with the transition to a new medical records software at the CSU Veterinary Teaching Hospital. Throughout her childhood and schooling, she developed a second passion - working with individuals with disabilities - and was an active part of several such organizations, including Best Buddies International.

Today, her professional interests are many, but she particularly enjoys dermatology, cardiology, and neurology, as well as small ruminant/camelid medicine and small animal nutrition, and is an active member of the American Associates of Bovine Practitioners and Small Ruminant Practitioners.

Dr. Ellen has been part of the Colmey Veterinary Hospital family since 2020 and purchased the practice from Dr. Colmey in 2023. She is happy to be an active part of the Livingston community and is grateful for the opportunity to help her neighbors and their animals. Dr. Ellen and her husband, Jacob, enjoy taking advantage of the Montana lifestyle, including hiking, camping, and hunting. They dream of having a small hobby farm with alpacas and dairy goats and training pack llamas. To learn more about Dr. Holbrook and the history of CVH, read about Our Story.

Veterinary Technicians and Assistants

Corbin H., LVT

Lead Veterinary Technician

My pup, Darla, and I moved out here in 2019 with no plan other than to just figure it out. Colmey Veterinary welcomed me with open arms and has taught me everything that I know about the veterinary medicine world, for which I am so grateful. In our free time, Darla and I spend time doing whatever activity leads us outside to enjoy this beautiful state of Montana.

Hey y’all- I’m Corbin and will probably be the one that talks funny when you walk into the clinic. I’m a transplant from Danville, Virginia. I graduated from Virginia Tech in Wildlife Management, with the only vision being that I wanted to live in the Rockies at some point in my life.

Janell E.

Veterinary Assistant

Hello everyone! My name is Janell Edgemon and I have lived here going on 5 years now. I moved here from Nevada, a state that has shaped me into the person I am today. From packing mules through the Sierra Nevadas, obtaining

my bachelor's degree in Animal Science and running cattle on one of the biggest ranches, large animal and livestock vet medicine has become a passion of mine. I now live in the beautiful Paradise Valley with my two daughters and an array of barnyard animals, and I look forward to what this beautiful state has to offer.

Brittney A.

Veterinary Assistant

Hey there, I'm Brittney. I've lived my whole life in the beautiful town of Livingston. I'm very proud to be a 7th generation Montanan and to call this place home. I enjoy the many things this state provides, such as trail riding with my horses, off-grid camping trips, and floating the Yellowstone. Caring for and treating animals has been my long-time passion, and I'm honored to be working in this industry with the amazing vets here. I’m looking forward to this journey of serving this community and their cherished pets.

Hi everyone, I'm Rylee and I’m from Miles City, Montana. I kept myself occupied as a child by participating in 4-H, FFA, rodeo, track, hunting, and fishing. I attended Northwest College in Powell, Wyoming, after high school to earn my associate's degree in Agricultural Business and to judge livestock. I've always loved animals, and Colmey Veterinary allows me to keep showing people and their pets how much I care!
