Cassie Krause - Staff Trainer

Cassie Krause grew up in Virginia with a passion for working with animals. By the grace of her patient mother, household pets included dogs, cats, fancy hooded rats, fish and guinea pigs. Her first memories are visits to zoos and aquariums and to this day she will plan trips around the local zoos and aquariums. She graduated from Virginia Tech in 2010 with a Bachelor's of Science in Wildlife Sciences and minor in Biology. After graduation she started her animal training career with an internship at the Audubon Zoological Society in New Orleans, LA, where she began her foundation of operant conditioning while working with California sea lions. She continued on to a hands on training internship at Coral World Ocean Park in St. Thomas in the Virgin Islands with South American sea lions.

After a brief stint as a receptionist and veterinary assistant at an animal hospital, she next pursued an internship, then professional animal trainer position, at Gulf World Marine Park in Panama City Beach, FL in 2012. There she lead daily presentations and encounter programs with Atlantic Bottlenose dolphins, Roughed-toothed dolphins, California sea lions, African black-footed penguins, exotic parrots, and domestic cats, dogs and rats. Though she doesn't have a dog of her own, her 4 year old cat, Leo, keeps her on her toes and even knows a few adorable behaviors.
