Our Staff Members

Dr. Desmarais


Dr. Desmarais recently moved to Big Sky, MT from Bozeman, and is very excited to practice medicine within this beautiful location. She wanted to live and work in Big Sky to become part of a close-knit community by providing medical care for their pets. Dr. Desmarais first attended the University of Vermont where she earned degrees in Animal Science and Biology before obtaining her veterinary degree at North Carolina State University. She completed an internship at the Ontario Veterinary College in Guelph, Ontario.  This was followed by joining Northwest Veterinary Specialists where she worked as an Emergency and critical care veterinarian for 7 years, before transitioning to use her skills as a general practitioner. Her veterinary interests include internal medicine, acupuncture, wound care, and trauma.


Dr. Desmarais has a passion for volunteering within her community and abroad. This interest began in vet school by conducting infectious disease research in Ethiopia and Cameroon.  More recently, in 2015 she volunteered with Dharamsala Animal Rescue in India and she spent a month in Thailand at the Soi dog foundation in 2014. Dr. D enjoys travelling to experience other cultures and learn how animals play unique roles within them. These experiences have expanded her problem solving skills and taught her many lessons useful to everyday medicine. 

Outside of her time at the clinic, you can find Dr. Desmarais in the mountains, whether it’s trail running, walking with her dog Loux, skiing, biking, climbing or camping. She also loves spending time with her family in Colorado.  

Ashely Barber

Certified Veterinary Technician

Ashley has called the beautiful mountains of Montana home since 2017.  As a lifelong lover of everything that walks on four legs, Ashley fed her passion by volunteering at local humane societies while studying Journalism at UW Eau Claire. Eventually, Ashley realized that the overwhelming love she has always had for animals was not arbitrary, it was a calling. She decided that she wanted to dedicate herself to helping our fuzzy friends and the people that love them. Ashley returned to school and became a Certified Veterinary Technician. After school, she spent time at a Wildlife Center and worked in Emergency Medicine before coming to LPV. She absolutely loves working in a clinic that is dedicated to providing an exceptional level of care, while maintaining a friendly and down to earth environment. When Ashley isn't working with the adorable animals of Big Sky, you can find her hiking, backpacking, skiing, climbing, or curled up on the couch with a good book and her beloved kitty, Korky. 

Anna Barry

Client Care Specialist

Anna is originally from Washington state but has been in Bozeman for 10 years. She has always had an interest in medicine but only recently took the plunge into the animal science world. She is interested in becoming a Veterinary Technician but for now she is excited to be working with the amazing staff and clients at Lone Peak Veterinary hospital and learning as much as she can. In her free time, Anna likes to be in the mountains chasing waterfalls with her dog, Koda, and fiance, Brock, playing hockey or working on her shuttle bus that she is converting to be her home!
