The Staff

Dr. Desmarais
Dr. Desmarais started Lone Peak Veterinary Hospital in 2017, after working in Bozeman and the surrounding areas for 2 years. She wanted to transition to working in a small, close-knit community where she could focus on high quality medicine and personalized care. She feels extremely lucky to a part of this incredible mountain town.
She first attended the University of Vermont for her undergraduate education before obtaining her doctor of veterinary medicine degree from North Carolina State University. Dr. D completed an internship at Ontario Veterinary College followed by numerous years working as an ER veterinarian at Northwest Veterinary Specialists in Portland, Oregon. Her veterinary interests include internal medicine, infectious disease and wound care.
Dr. Desmarais has a passion for volunteering within her community and abroad. She had previously volunteered in India and Thailand, treating and performing surgeries on street dogs. Within Big Sky, she started RUFF – Riley’s Urgent Fund for Friends – a non-profit assistance fund to help subsidize healthcare for animals in need. She is so excited about the community's response to help!
We look forward to meeting you and your pets!

Mallory
Hi, I’m Mallory! I just moved here from Kentucky; however, I’m originally from Illinois. I currently have one dog, named Mo. I enjoy reading and embroidery when I’m not in the clinic. I have been in the field for 3-4 years working in both Illinois and Kentucky. I’m excited to see what Montana has to offer!
