Dr. Brittany Rainey

DVM

Dr. Brittany was born and raised in Orange County, California. Ever since she can remember, she was always that kid in class who loved to read and dream about animals, particularly horses. As a result, Dr. Brittany developed a love for animals at an early age and dreamed about one day becoming a veterinarian and owning a Siberian husky. Her love of horses led her to enroll at Cal Poly Pomona, where she could work with their Arabian horses. Since she was able to commute to school from home, she did not have to leave her huskies behind.

After graduating from Cal Poly Pomona with a BS in Animal Science, Brittany continued to commute to Pomona for the next four years to attend Western University of Health Sciences, from which she graduated with a DVM in 2019.

Dr. Brittany’s interests in medicine include internal medicine, infectious disease, nutrition, and a particular interest in reproductive medicine. Even though she loves working with small animals, she welcomes the occasional opportunity to treat a horse or a goat.

Dr. Brittany’s personal interests include a love of reading and collecting Loungefly bags and Funko pop figurines; she’s a self-professed nerd. She has two Siberian huskies and is getting ready to start showing them once their training is complete. She is also owned by several rescue cats. In the little spare time that she has, Dr. Brittany traps, neuters, and releases cats from the feral cat population in her immediate neighborhood and would love to one day start a cat rescue.
