Additionally, she was charged with managing interns at a large specialty hospital. She is now proud to be the independent owner of her own practice in Marin.

Her early education includes training as a veterinary technician and a diploma in animal behavior and training (including elephant training) — two fields she worked extensively in while pursuing her Doctorate at UCDavis.

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. Additionally, she believes only in gentle animal handling and trains her staff in ways to reduce stress.

Emmanuelle Hill, Veterinary Assistant

Hello, I’m Emmanuelle, a dedicated veterinary assistant on the path to a 4-year veterinary school journey. My passion for animals led me to switch from psychology to Animal Biology in 2020. Inspired by my Pug, Omar, I dream of opening a non-profit clinic, specializing in brachycephalic animals with a focus on soft palate/airway surgery, treating sick strays, and providing care, for free, and at a low cost.

Outside the clinic, you’ll find me singing, gardening, and enjoying quality time with loved ones. I have a soft spot for fostering kittens through various programs, providing a loving home whenever I can. I find solace in rainy, stormy days, and my favorite color is pink. My goal is to provide every pet with the best care, ensuring they feel the warmth of extra blankets, indulgent treats, and the love they deserve. Rest assured they’ll receive the utmost care and affection in my hands.
