Lisa Shender, D.V.M., M.S., Ph.D.
When Dr. Shender first applied to veterinary school, her intent was to begin in the fall after graduating with her B.S. in Biology from the University of California, Davis (UCD). Her first attempt resulted in rejection with a veterinary program counselor advising her that “wanting to be a wildlife veterinarian is trendy” and that her application didn’t demonstrate the experience to back up her desire. Taking this in stride, Lisa took Route B and enrolled in a master’s degree program in Wildlife Sciences at Humboldt State University (HSU). During school, she obtained a fellowship from the Welder Wildlife Foundation to study parasitology of feral pigs in Texas. After graduating from HSU and a couple of stints studying sea turtles in Panama, Lisa matriculated into the 2004 UCD class of Veterinary Medicine. Following graduation, she worked for the Arizona Game & Fish Department for four years as the Wildlife Health Specialist. Eventually, she realized that without additional analytical skills, it would be difficult for her to evaluate wildlife health and disease trends. So back to UCD she went, this time to earn a doctorate in Wildlife Epidemiology. A 3-year grant from the Foreign Animal Zoonotic Disease Defense Center facilitated Lisa’s research on leishmaniasis in Peru. The second part of her doctoral research focused on Trypanosoma cruzi (causative agent of Chagas disease) in rodents and vectors in California. Since completing her Ph.D., Lisa has finally settled in Florida, where she works for the Florida Fish & Wildlife Conservation Commission.  Dr. Shender can be contacted at

, Treasurer
Dr. Ballard has been involved with the American Association of Wildlife Veterinarians since 2008. She studied Wildlife Management at Arkansas Tech University before attending veterinary school at the University of Missouri. Following veterinary school, Jenn worked as a diagnostician at the Southeastern Cooperative Wildlife Disease Study while earning a Ph.D. in Veterinary & Biomedical Science studying Wellfleet Bay virus in the common eider. Jenn then spent two years with the US Fish and Wildlife Service as a veterinarian for the National Wildlife Refuge System before becoming State Wildlife Veterinarian with the Arkansas Game & Fish Commission. Jenn lives with her husband, son, and two dogs outside of Little Rock, Arkansas. Dr. Ballard can be contacted at
