Bret Peterson, DVM

Owner and Veterinarian

Dr. Bret Peterson grew up near Chicago, which is when he developed his love for the Chicago Cubs. He earned his Bachelor’s in Biology from Knox College and his doctorate of veterinary medicine from Iowa State University. Dr. Peterson worked as a veterinarian in Wisconsin before relocating to Springfield where he was hired as a relief vet for Laketown Animal Hospital. Dr. Peterson’s special interest in soft tissue and orthopedic surgery, along with Laketown’s  state of the art surgical suite made for a great partnership and he decided to become full time shortly thereafter. During his free time he enjoys woodworking and spending time with his wife and daughter. They especially enjoy beach days where they can rediscover the simple pleasures through their daughter’s eyes such as building sandcastles and playing in the waves. They recently adopted a kitten, named Meowy.
