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!



Originally from Darien, Connecticut, Nell moved to Montana in 2010 to study Fish and Wildlife Management at MSU and after graduating in 2015 decided it wasn’t quite time to leave. Nell has taught for over 10 years with a variety of ages and curriculums such as wildlife education at the Bronx Zoo and with Montana Outdoor Science School, and Montessori preschool in Bozeman but realized she was ready to get back to working with animals and is thrilled to be part of the Lone Peak Vet team. When not working at LPV, Nell loves skiing, climbing, painting, volunteering at the Montana Raptor Conservation Center, and exploring with her two dogs Smith and Sky and partner Justin. Nell is excited for all that is to come being a part of this team and community.
