Growing up in Australia, Dr. Shay Redfield began her life-long love of animals. Her first internship in high school was with a flying vet serving the outback. From bringing home strays to rescuing a koala from dogs or a kangaroo from the local library, Shay always thrived when animals needed help.

Dr. Shay Redfield loves being a veterinarian, and she strives to inspire the next generation. She is dedicated to helping animals at all life stages, but takes a particular interest in caring for aging pets.
