Because of her interest in animals, she chose to pursue a Bachelor's degree in Biology at Pacific Lutheran University. She then went on to work at several area veterinary clinics before joining the staff at Pine Tree Veterinary Hospital.

Over the years Cas has had a number of amazing animal experiences: she's ridden a horse valued at a worth exceeding most cars, swam with dolphins, hugged an orca, trained an ibis, kissed a sea lion, held a small shark, and scuba dived with a legendary Puget Sound giant pacific octopus!! As if that weren't enough animal adventure for any one person, she has also fed a baby bengal tiger, held a 150 pound anaconda snake, and released endangered baby sea turtles off the beaches of Mazatlán into the Pacific Ocean.

Cas and her husband Brandon keep and breed several species of snakes including pythons, boas, and rat snakes, as well as their two pet dogs and a cat.

Chelsey would love to continue her education at the University of Washington, at the Bothell campus, to obtain a bachelors degree in biology, then later go to vet school to major in exotics.
