The mission of the Brookfield Zoo Chicago's Veterinary Services Department is to provide a visionary level of veterinary care to our patients, to inspire people  of all backgrounds, and to passionately advance the  professional standards for zoological medicine in a way  that positively impacts the conservation of wildlife and  nature. The department’s current programs focus on three core areas of strength: medical imaging, anesthesia and  analgesia, and veterinary education.
