Dr. Donna M. Lewis, DVM: Clinic Owner/Veterinarian

Dr. Donna was born and raised in Hamilton and the Grantsdale area. She enjoyed pack trips in the Bitterroot and Pintlar ranges growing up. During high school at Hamilton High School she spent much time in Mrs. Virginia Vinal’s choir room, loving music and all activities associated with it. She graduated from the University of Idaho with a BS in Animal Science and a minor in Music Education. Her love of animals and science took her on to veterinary school at Washington State University, graduating in 1993. She started her vet career in a mixed animal practice in Moscow, ID where she worked for 8 years. She and her husband Ron raised 2 girls in Moscow. Over time Donna spent 12 years in the field of Laboratory Animal Veterinary Medicine at Washington State University (10) and Montana State University (2). Now she loves being back home in the Bitterroot in private veterinary practice. She lives with her family and pets including 1 busy German Shepherd “Steel”, 4 cats, 4 cows, and a bunch of chickens. It’s wonderful to be back home in the Valley!
