Dr. Lisa Done, MPVM

Associate Veterinarian


Dr. Lisa Done has enjoyed science, medicine, and problem-solving for as long as she can remember. As a veterinarian, she’s able to use her skills every day to better the lives of pets and animal owners!

Dr. Done grew up in Orange, California. After moving to Maryland, she was accepted into the fifth class at the Virginia-Maryland Regional College of Veterinary Medicine at Virginia Tech in Blacksburg, Virginia. Dr. Done has worked in private practice, research, laboratory animal medicine, zoological medicine, and equine anesthesia and large-animal intensive care at two veterinary medical teaching hospitals. As a Technician at the San Antonio zoo—when zoo medicine was in its infancy—she even helped to treat an immobilized Nile hippopotamus, which sparked a life-long quest to obtain further knowledge regarding unusual animal species and their unique health concerns. Dr. Done has also recently become board-eligible for the American College of Zoological Medicine.

Dr. Done joined the Veterinary Angels Medical Center family in July of 2015, and has a special passion for treating exotic creatures thanks to her varied animal-care background. The more challenging the case, says Dr. Done, the better.

Dr. Done and her husband, who works as a small-animal veterinarian himself, live with three pets: Nala, a Siamese cat; Raffles, a Senegal parrot; and a rescued Chihuahua named Bug. In her time away from work, Dr. Done enjoys traveling, photography, and videography.
