Tanner Thomas


 My fascination with animals started at a young age on my grandfather's horse ranch.  In college I worked with snakes at a venom lab. After college I worked with big cats and bears at a refuge, before working at 3 different zoos with a wide array of animals including Komodo dragon, hippo, and penguins. Eventually I became specialized in training large African hoofstock (Rhino, Giraffe, antelope). Finally I got to work with and train Asian Elephants. After that I retired from zookeeping and became a vet tech. In my free time I have been lucky enough to swim with some amazing wild animals including: sea turtles (3 species), sea lions, marine iguanas, Galapagos penguins and Whale Sharks!
