Terry J. Kreeger co-authored the Handbook for Wildlife Chemical Immobilization, which has become the go-to reference for the field. For 20 years, Terry was the chief veterinary officer of the Wyoming Game and Fish Department. Terry was also the past president of the American Association of Wildlife Veterinarians. He holds Bachelor degrees in Journalism and Veterinary Science, a Master’s degree in Wildlife Biology, a Ph.D. in Wildlife Management, and is a Doctor of Veterinary Medicine. He is also an Adjunct Professor at the University of Wyoming (Veterinary Sciences) and the University of Minnesota (Fisheries and Wildlife).

His research interests include wildlife capture and anesthesia, physiology and behavior, animal contraception, and wildlife diseases. He has captured dozens of species in the field, from antelope to zebras and has trained hundreds of students and wildlife professionals throughout North America, Russia, Africa, and Asia. In 2016, he was unanimously elected a lifetime Honorary Member of The Wildlife Society. Dr. Kreeger has authored over 100 scientific publications, books, and chapters, half of which dealt with chemical immobilization of wildlife.
